Single user unable to authenticate with LDAP

Hi!

I got quite a mystery on my hands. I've setup SugarCRM for 50 users, where 49 of them can authenticate with LDAP...

I got one user that simply is unable to login with ldap.

[ERROR] User was not found by provided name

What does the last logline mean here? The same ldap configuration works for all my other services and the user in question logs in just fine with the rest of my 50 users
