[Samba] Problem with mixed-case usernames and group mapping

[Gustavo Noronha Silva]

Hello,

I've got a problem with user<->group mapping. Our windows PDC has 
mixed-case usernames. 'getent passwd' is ok, as it simply ignores case 
and shows all users in lowercase, but 'getent group' will give me 
'group: User,User2', so when I 'id user' it will not be shown as member 
of 'group'.

A simple example:

# getent passwd fernando.rodrigues
fernando.rodrigues:[...]:Fernando Rodrigues Mendonca:[...]
# getent group cgmi
cgmi:[...]:gustavo.silva,Fernando.Rodrigues,Marcelo.Pellicano,[...]
# id fernando.rodrigues
[...] gid=10000(Domain Users) grupos=10000(Domain Users)

Any ideas?

Thanks,
