- lib/sids.c:
generate_sam_sid() modified to take a domain name: it now
generates "DOMAIN_NAME.SID". reasons:
1) if you run multiple samba servers on the same machine
under different netbios names as members of a domain,
they won't all use the same SID, which is a _big_ mistake
but it would happen _by default_.
2) we have (had) a problem with sid_to_string() and string_to_sid()
which cause SIDs to be incorrectly read. one of the major
reasons for *NOT* making this change was so as not to disrupt
existing users. but as they will be anyway by this bug,
we might as well go ahead.
- passdb/smbpass.c:
wanted to change the meaning of the name in the smbpasswd
file to an "nt" name not a "unix" name. this is probably
not a good idea: reverted this.
- output formatting / bug-fixing in rpcclient query_useraliases code.
