Configure MongoDB Agent for LDAP¶

On this page

Prerequisites
Create and Configure User in MongoDB

If your MongoDB deployment enforces access control, the MongoDB Agent must authenticate to MongoDB as a user with the proper access. If you use Automation, Ops Manager takes care of this for you.

MongoDB Enterprise supports simple and SASL binding to LDAP servers via saslauthd and operating system libraries:

MongoDB Enterprise for Linux can bind to an LDAP server either via saslauthd or via operating system libraries.
MongoDB Enterprise for Windows can bind to an LDAP server via the operating system libraries.

MongoDB Agent support authenticating to MongoDB instances using LDAP.

Note

With Automation, Ops Manager manages MongoDB Agent authentication for you. To learn more about authentication, see Enable LDAP Authentication for your Ops Manager Project.

Prerequisites¶

Configure Deployments to Use Authentication¶

The MongoDB Agent interacts with the MongoDB databases in your deployment as a MongoDB user would. As a result, you must configure your MongoDB deployment and the MongoDB Agent to support authentication.

You can specify the deployment’s authentication mechanisms when adding the deployment, or you can edit the settings for an existing deployment. At minimum, the deployment must enable the authentication mechanism you want the MongoDB Agent to use. The MongoDB Agent can use any supported authentication mechanism.

Considerations¶

If Automation does not manage your deployment, you must configure LDAP authentication separately for each function.

To configure LDAP authentication, add a host or edit an existing host’s configuration.

Create and Configure User in MongoDB¶

Deployments Managed by Automation
Deployments Not Managed by Automation

To automate MongoDB instances that use LDAP authentication, add a MongoDB user that possesses the required roles and privileges to the $external database in MongoDB. The $external database allows mongod to consult an external source, such as an LDAP server, to authenticate.

Use the following commands to create the users from a mongo shell connected to your MongoDB deployment:

copy

   db.getSiblingDB("$external").createUser(
     {
       user : "<username>",
       roles : [ 
         { role : "clusterAdmin", db : "admin" },
         { role : "readWriteAnyDatabase", db : "admin" },
         { role : "userAdminAnyDatabase", db : "admin" },
         { role : "dbAdminAnyDatabase", db : "admin" },
         { role : "backup", db : "admin" },
         { role : "restore", db : "admin" }
       ]
     }
   )

To learn more about the required access, see Required Access for MongoDB Agent.

Backup
Monitoring

To back up MongoDB 2.6 or later instances that use LDAP authentication, add a user that possess the required roles to the $external database in MongoDB. The $external database allows mongod to consult an external source, such as an LDAP server, to authenticate.

Use the following commands to create the users from a mongo shell connected to your MongoDB deployment:

MongoDB 3.0 or later
MongoDB 2.6

copy

db.getSiblingDB("$external").createUser(
    {
      user : "<username>",
      roles: [ { role: "backup", db: "admin" } ]
    }
)

copy

db.getSiblingDB("$external").createUser(
   {
     user: "<username>",
     roles: [
        "clusterAdmin",
        "readAnyDatabase",
        "userAdminAnyDatabase",
        { role: "readWrite", db: "admin" },
        { role: "readWrite", db: "local" },
     ]
   }
)

To learn what roles this function requires, see Required Access for MongoDB Agent.

To monitor MongoDB 2.6 or later instances that use LDAP authentication, add a user that possess the required roles to the $external database in MongoDB. The $external database allows mongod to consult an external source, such as an LDAP server, to authenticate.

Use the following commands to create the users from a mongo shell connected to your MongoDB deployment:

copy

db.getSiblingDB("$external").createUser(
    {
      user : "<username>",
      roles: [ { role: "clusterMonitor", db: "admin" } ]
    }
)
