VA-003 Compare authentication methods Practice Question
A Vault administrator needs to allow users to authenticate using their existing corporate Active Directory credentials. The administrator has configured the LDAP authentication method but users cannot log in. The Vault logs show 'LDAP bind successful' but then 'user not found in group' error. What is the most likely issue?
⚠ Common exam trap
HashiCorp often tests the distinction between authentication (bind) and authorization (group lookup) — candidates mistakenly focus on the bind success and assume the issue is with user attributes or server connectivity, when the real problem lies in the group membership configuration.

Correct answer & explanation
✓
The groupfilter or groupattr configuration is incorrect
The error 'LDAP bind successful' confirms that the Vault server can connect and authenticate to the LDAP server using the bind credentials. The subsequent 'user not found in group' error indicates that while the user exists and can bind, the group membership lookup fails. This is most commonly caused by an incorrect `groupfilter` or `groupattr` configuration, which defines how Vault queries the LDAP directory to map users to groups for authorization.

- ✗
The LDAP server hostname is incorrect
Why it's wrong here

Group membership check fails after bind.
