Users are registered in an LDAP

Validate in the database the user, and if it is found, also synchronize with the activity directory. 

 

Do you have any idea what is happening?

Hi there, Miguel.

Since you mentioned that the user exists in the database, can we first run a SELECT statement on the database so we can see if there is anything different compared to normal users who can authenticate to Confluence?

SELECT * FROM cwd_user WHERE lower_user_name='<username>';

SELECT * FROM user_mapping WHERE lower_username='<username>';

Additionally, was the user account able to log in before this issue occurs or it is the first time that you are trying to access Confluence using this account?

• If it is the first time, may I know if you can run a full sync and flush all the cache to confirm if the user is still facing the same issue?
• If it is not the first time, do you recall any changes made to this account before the problem surfaces?

Looking forward to hear from you soon.
