Failed to authenticate

I have a user who is not able to login into one of the servers. However another server, which belongs to the same cluster (so should be identical) allow him to login with no problem. The error message in notes log is here:

10/06/2006 02:30:11 PM USERNAME from host [HOST] failed to authenticate: Your account is locked out; see your system administrator to reset it

The user has the same message in the popup window when he tries to open the first server. The Address Book is the same. He is using the same id file.

I would appreciate any advice on what to do to force this to work.

In this case, the issue was resolved by running Fixup, Updall and Compact against the Domino Directory.

Hi Juan,I performed Fixup and Compact and it didn’t help.

Just in case tried an old backup ID and it worked without error. Any explanation on that? It would be nice to understand what was happening.

Thanks!
