SASL AUTHENTICATION SYNOPSIS GENERAL AUTHENTICATION REBINDING

On this page

MongoDB Enterprise supports querying an LDAP server for authdefault error ldap_bind LDAP groups to which the authenticated user belongs. MongoDB maps the distinguished names (DN) of each returned group to roles on the database. MongoDB authorizes the user based on the mapped roles and their associated privileges. See LDAP Authorization for more information.

The LDAP Authorization process is summarized below:

  1. A client connects to MongoDB and performs authentication with any authentication mechanism that supports external authentication.

    To use Client Sessions and Causal Consistency Guarantees with authentication users (Kerberos, LDAP, or x.509 users), usernames cannot be greater than 10k bytes.

  2. MongoDB binds to the LDAP server specified with using the credentials specified with and .

    MongoDB uses simple binding by default, but can use binding instead if configured in and .

  3. MongoDB constructs an LDAP query using the and queries the LDAP server for the authenticated user's group membership.

    MongoDB can use the option to transform the username for supporting the query template.

  4. The LDAP server evaluates the query and returns the list of groups to which the authenticated user belongs.

  5. MongoDB authorizes the user to perform actions on the server by mapping each returned group's Distinguished Name (DN) into a role on the squidclamav error c-icap-config not found database. If a returned group DN exactly matches the name of an existing role on the database, MongoDB grants the user the roles and privileges assigned to that role. See MongoDB Roles for LDAP Authorization for more information.

  6. The client can perform actions on the MongoDB server which require the roles or privileges granted to the authenticated user.

  7. At an interval defined byMongoDB flushes the cache. Prior to executing subsequent operations performed by externally authorized users, MongoDB re-acquires their group membership from the LDAP server.

A full description of LDAP is beyond the scope of this documentation. This page assumes prior knowledge of LDAP.

This documentation only describes MongoDB LDAP authorization, and does not replace other resources on LDAP. We encourage you to thoroughly familiarize yourself with LDAP and its related subject matter before configuring LDAP authentication.

MongoDB can provide professional services for optimal configuration of LDAP authorization for your MongoDB deployment.

The following authentication mechanisms are compatible with MongoDB LDAP authorization:

Starting in version 4.2.0, when connecting to the LDAP server for authentication/authorization, MongoDB, authdefault error ldap_bind, by default:

  • Uses connection pooling if run:

    • on Windows or

    • on Linux where MongoDB Enterprise binaries are linked against libldap_r.

  • Does not use connection pooling if run:

    • on Linux where MongoDB Enterprise binaries are linked against libldap.

To change the connection pooling behavior, update the parameter.

For MongoDB 4.2 (and 4.0.9) Enterprise binaries linked against (such as when running on RHEL), authdefault error ldap_bind, access to the is synchronized, incurring some performance/latency costs.

For MongoDB 4.2 (and 4.0.9) Enterprise binaries linked againstauthdefault error ldap_bind, there is no change in behavior from earlier MongoDB versions.

With LDAP authorization, user creation and management authdefault error ldap_bind on the LDAP server. MongoDB requires creation of roles on the database, with the name of each role exactly matching a LDAP group Distinguished Name (DN). This is in contrast to MongoDB managed authorization, which requires creating users on the database.

To manage roles on the MongoDB server, authenticate as a user whose group membership corresponds to a database role with role administration privileges, such as those provided by. Create or update roles corresponding to LDAP group DNs such that users with membership in that group receive the appropriate roles and privileges.

For example, an LDAP group for database administrators might have a role with administrative roles and privileges. An LDAP group for marketing authdefault error ldap_bind analytics authdefault error ldap_bind may have a role with only have read privileges on certain databases.

Important

When configuring a role for authdefault error ldap_bind corresponding LDAP Group, remember that all users with membership in that group can receive the configured roles and privileges. Consider applying the principle of least privilege when configuring MongoDB roles, LDAP groups, or group membership.

If no role with role administration privileges exists AND no non- user with these privileges exists, you effectively cannot perform user management, as no new or existing roles can be altered to reflect additions or changes to groups or group membership on the LDAP server.

To remedy a scenario where you cannot manage roles on the MongoDB server, perform the following procedure:

  1. Restart the MongoDB server without authentication and LDAP authorization

  2. Create a role on the database whose name corresponds to the appropriate LDAP group Distinguished Name, authdefault error ldap_bind. When choosing a group DN, authdefault error ldap_bind which group is most appropriate for database administration.

  3. Restart the MongoDB server with authentication and LDAP authorization

  4. Authenticate as a user with membership in the group corresponding to the created administrative role.

A MongoDB server using LDAP for authorization makes any existing users on the database inaccessible. If there are existing users in database, you must meet the following requirements for each user on the database to ensure continued access:

  • User has a corresponding user object on the LDAP server

  • User object has membership in the appropriate LDAP groups

  • MongoDB has roles on the database named for the user's LDAP groups, such that the granted roles and privileges are identical to those granted to the non- user.

If you want to continue allowing access by users not on the database, ensure the parameter includes and/or as appropriate. Alternatively, apply the requirements listed above for on error goto err_ those users to LDAP authorization.

For replica sets, authdefault error ldap_bind, configure LDAP authorization on the secondary and arbiter members first before configuring the primary. This also applies to shard replica sets, or config server replica sets. Configure one replica set member at a time to maintain a majority of members for write availability.

In sharded clusters, you must configure LDAP authorization on the config servers for cluster-level users. You can optionally configure LDAP authorization on each shard for shard-local users.

You must configure the following settings to use LDAP Authorization:

To use LDAP for authorization via operating system libraries, authdefault error ldap_bind, specify the following settings as a part of your or configuration file:

Option

Description

Required

Quote-enclosed comma-separated list of LDAP servers in format.

YES

An RFC4515 and RFC4516 LDAP formatted query URL template executed by MongoDB to obtain the LDAP groups to which the user belongs to. The query is relative to the host or hosts specified in .

You can use the following tokens in the template:

  • Substitutes the authenticated username, or the username, into the LDAP query.
  • Substitutes the supplied username, i.e. before either authentication or LDAP transformation, into the LDAP query. (Available starting in version 4.2)

Only supports this parameter. defers to this setting as authdefault error ldap_bind on its config servers

YES

The identity the MongoDB server binds as when connecting to and executing operations and queries on an LDAP server.

Use with .

The user specified must have the appropriate privileges to support the LDAP queries generated from the configured .

YES

The password used to bind to an LDAP server when using .

YES

NO, unless using for binding to the LDAP server.

Used to specify the SASL mechanisms or can use when authenticating or binding to the LDAP server. MongoDB and the LDAP server must agree on at least one SASL mechanism.

Defaults to .

NO, unless setting toand you need different or additional SASL mechanisms.

Windows MongoDB deployments can use the operating system credentials in place of and for authenticating or binding as when connecting to the LDAP server.

NO, unless replacing authdefault error ldap_bind and .

Depending on yourthe authenticated client username may require transformation to support the LDAP query URL. allows MongoDB to transform incoming usernames.

NO, unless client usernames require transformation into LDAP DNs.

MongoDB uses the to create an RFC4516 formatted LDAP query URL, authdefault error ldap_bind. In the template, you can use either:

  • placeholder to substitute the authenticated username into the LDAP query URL. If MongoDB transformed the username usingMongoDB replaces the token with the transformed username when constructing the LDAP query URL.

  • placeholder to substitute the supplied username, i.e. before either authentication or LDAP transformation, into the LDAP query.

Design the query template to retrieve the user's groups.

Example

The following query template returns any groups listed in the LDAP user object's attribute. This query assumes the attribute exists - your specific LDAP deployment may use a different 0x51 registry error vista or methodology for tracking group membership, authdefault error ldap_bind. This query also assumes the user authenticates using their full LDAP DN as their username.

The LDAP query URL must conform to the format defined in RFC4516:

Consider the definition of each component, as quoted from RFC4516:

The is an LDAP Distinguished Name using the string format authdefault error ldap_bind in RFC4514. It identifies the base object of the LDAP search or the target of a non-search operation.

The construct is used to indicate which attributes should be returned from the entry or entries.

The construct is used to specify authdefault error ldap_bind scope of the search to perform in the given LDAP server. The allowable scopes are "base" for a base object search, "one" for a one-level search, or "sub" for a subtree search.

The is used to specify the search filter to apply to entries within the specified scope during the search, authdefault error ldap_bind. It has the format specified in [RFC4515].

The construct provides the LDAP URL with an extensibility mechanism, allowing the logical block 0 error of the URL to be extended in the future.

If the query includes anMongoDB assumes the query retrieves a the Sprint error 97 sms which this entity is member of.

If the query does not include an attribute, MongoDB assumes the query retrieves all entities for which the user is member of.

MongoDB currently ignores any extensions specified in the LDAP query.

Important

A full description of RFC4516 or LDAP query URL construction is out of scope for this documentation.

The following tutorials contain procedures for connecting to an LDAP server via the Operating System LDAP libraries:

When using LDAP for authorization, users connecting via bind error 7d the and of the MongoDB server, along with any other options relevant to your deployment.

For example, the following operation authenticates to a MongoDB server running with LDAP authentication and authorization:

If you do not specify the password to the command-line option, authdefault error ldap_bind, prompts for the password.

Important

The argument must be placed in single quotes, not double quotes, to socket error # 11002 jane style the shell from interpreting as a variable.

MongoDB maps each returned group distinguished name (DN) returned by the LDAP to a role on the database.

If MongoDB acquires a group whose DN exactly matches the name of an existing role, MongoDB grants the authenticated user roles and privileges associated with that role. If MongoDB cannot map any of the returned groups to a role, MongoDB grants no privileges to the user.

Note

LDAP and kerberos authentication normally require creating users in the database. If you also use LDAP for authorization, you do not need to create users in the database. You only need to create the appropriate roles in the database, authdefault error ldap_bind. Users still authenticate against the database.

Important

If you are using LDAP for authorization and your LDAP group DNs contain RFC4514 escaped sequences, the roles you create in the database must also be escaped following RFC4514.

Example

A database has the following roles configured on the database:

After authenticating a user against the database, the MongoDB server performs a query derived from the configured to retrieve the groups which include the authenticated user as a member. In this example, the MongoDB server retrieves the following group DNs for the user:

MongoDB maps these group DNs to roles on the database. The first group DN matches the first role, and MongoDB grants the authenticated user its roles and privileges. The second group DN does not match to any role on the server, so MongoDB grants no additional permissions.

A new user authenticates against the database. The MongoDB server repeats the query process, using the provided username in the query template. In this example, the MongoDB server retrieves the following group DNs for the user:

MongoDB maps these group DNs to roles on the database and grants the authenticated user the roles and privileges of the second role.

A new user authenticates against the database. The MongoDB server repeats the query process, using the provided username in the query template. In this example, the MongoDB server retrieves the following group DNs for the user:

MongoDB maps the group to a role on the database and, authdefault error ldap_bind, because no matching roles exist, grants the user no additional permissions.

These errors indicate your LDAP server is configured to Require Signing, authdefault error ldap_bind. UnitySync, however, does not perform data signing. With this requirement configured on the LDAP directory, UnitySync fails to bind to the server and returns the error shown above.

Solution

Per a Microsoft TechNet article:

Domain controller: LDAP server signing requirements

This security setting determines whether the LDAP server requires signing to be negotiated with LDAP clients, as follows:

None: Data signing is not required in order to bind with the server. If the client requests data signing, the server supports it.

Require signature: Unless TLS\SSL is being used, the LDAP data signing option must be negotiated.

Default: Not defined, authdefault error ldap_bind, which has the same effect as None.

Per the TechNet article, if you connect using SSL, data signing is not required.

Ask your Active Directory Administrator if SSL is enabled on the AD server. You can test with the SSL LDAP port of 636 (instead of the standard ldap port of 389) to see if that resolves the problem.

If SSL is disabled, you will need to reset the Signing Requirements setting to NONE, authdefault error ldap_bind. Then, using the standard LDAP port of 389, try the Test Connection again. With signing turned off, the connection should be successful.

Strong Authentication: Error message “Server requires binds to turn on integrity checking if SSL\TLS are not already active on the connection”

2017-05-08 17:00:41

Error text

When utilizing the Test functionality on the Destination tab and are configured to use LDAP port 389, you receive an error that reads:

Or, when you attempt to Sync using LDAP port 389, you receive an error that reads:



These errors indicate your LDAP server is configured to Require Signing. UnitySync, however, does not perform data signing. With this requirement configured on the LDAP directory, UnitySync fails to bind to the server and returns the error shown above.

Solution

Per a Microsoft TechNet article:

Domain controller: LDAP server signing requirements

This security setting determines whether the LDAP server requires signing to be negotiated with LDAP clients, as follows:

None: Data signing is not required in order to bind with the server. If the client requests data signing, the server supports it.

Require signature: Unless TLS\SSL is being used, the LDAP data signing option must be negotiated.

Default: Not defined, which has the same effect as None.

Per the TechNet article, if you connect using SSL, data signing is not required.

Ask your Active Directory Administrator if SSL is enabled on the AD server. You can test with the SSL LDAP port of 636 (instead of the standard ldap port of 389) to see if that resolves the problem.

If SSL is disabled, you will need to reset the Signing Requirements setting to NONE. Then, using the standard LDAP port of 389, try the Test Connection again. With signing turned off, the connection should be successful.
