Fix Recommendation

When using Active Directory synchronization, as is required by this STIG, User Roles assignments are assigned by LDAP sync. AD security groups correlate, one to one, to Tanium User Roles.

To change a Tanium user's User Functional Role, their Active Directory account needs to be moved to the AD security group, which correlates with the applicable User Functional Role.

Access the Active Directory server.

Locate the account(s), which have been determined to have the incorrect User Functional Roles in Tanium.

Review the Tanium-related AD Security Groups to which the user account(s) belong that directly correlate to the incorrect Tanium User Functional Roles.

Remove the user account(s) from the incorrect Tanium User Roles, ensuring the user account(s) are still members of the Tanium-related AD Security Groups for which they have been documented to be authorized.
