I think this is a side effect of the way various clients mangle the case
of passwords. In order to deal with this, samba needs to try with the
password as received, then forced lower case, then try other combinations
depending on the "password level" option in smb.conf.

It's a feature of the PAM library that these get logged, when on other
systems and previously on Linux they weren't. I think that you would need
to get PAM to understand the "password level" parameter and to do the
permutations and retries to avoid the excessive loging problem. Maybe
somebody is already working on this??

OTOH, based on the information in the smb.conf manpage, you wouldn't get
this behaviour if WfWg was using COREPLUS protocol rather than LANMAN1, so
you could try to force WfWg to use COREPLUS. I don't know how you do this,
or what other affects you would see.
