Winbind and uppercase domain name

[Buchan Milne]

It appears that PAM converts the full username to lowercase, resulting 
in certain problems with mis-matched interpretations of the username.

One example of this is trying to use pam_mount to mount a share at login 
time (to more or less emulate login scripts under linux). pam_mount can 
mount shares at login time using the supplied username and password, 
according to a config file, which can contain wildcards. For example, 
the line:

volume * smb granite mail /home/&/mail

Would mount //granite/mail on /home/domain+username/mail (since 
pam_mount expands & to the username from pam), whereas Winbind (via 
pam_mkhomedir) has created /home/DOMAIN+username (with template homedir 
= /home/%D+%U).

The other issue is that mail spool files are also typically lowercased.

Thus, would it not be preferable for winbind to return the full username 
in lowercase? It is probably possible to fix pam_mount to expand a home 
directory, but  if pam is lowercasing usernames, either pam needs to be 
fixed so it does not lowercase usernames, or winbind should no use 
uppercase in the username.

Support for a default domain would actually solve this problem in most 
cases.
