We're using LDAP for Jenkins, and have a bunch of users that are disabled, they also coincide with the names of some jobs, so e.g. the "machine" user would have some context to the "machine_.."-jobs, and would exist in LDAP.

Now, we've moved on and disabled the "machine" user, but when we want to find the "machine_.." jobs, by searching for "machine" We're sent to the login screen, and in the logs we find an error, like:

org.springframework.security.authentication.DisabledException: The user "machine" is administratively disabled. 

I'll post the full error in a comment below.

Searching for `mach` or `machine_` correctly returns results. But when the name exactly matches, the error happens.
