Description Nils Philippsen 2009-04-15 12:07:11 EDT
Description of problem:
When attempting to prohibit e.g. logins with a supplied uppercase user name, this won't work with users coming out of ADS because winbindd (via nss_winbind) converts the supplied user name to lower case.

Version-Release number of selected component (if applicable):

How reproducible:

Steps to Reproduce:
1. have a user in ADS, integrated via winbind
2. auth sufficient user !~ [*[A-Z\]*]
3. Try to login via ssh, supplying at least one capital character in the user name
Actual results:
Logging in works, "user ... met requirement" in the log

Expected results:
Logging in doesn't work
