[Samba] Memory Leak in 2.2.6rc2??

Hi Jerry,

i just pulled an all-nighter doing a re-org of all our servers which gave me
an opportunity to clean things up.

Thi ngs went well with once expection;  A clean install of RedHat 7.3 +
Samba 2.2.6 was an absolute fscking nightmare.

I could join the domain, wbinfo showed groups and users properly,
pam.d/samba, nsswitch.conf and smb.conf were configured identically with
another samba server that runs great.

What I ran into was:

 - getent would show only local groups
 - Win2k workstations connecting would only come in as nobody
 - shares would show up but double-clicking on a share would result in a
login dialog. 

I started with pre2 and worked up to rc3.  At some point things went really
haywire and I got the looping getent you describe.

In answer to your other questions:

The domain is mixed mode.
Winbind enum users and groups are explicitly specified
Server in question is dual PIII
No build options - straight from rpm.

the one thing I do notice is a noticeable pause when loggin in or for any
process requiring authentication (e.g. scp)

Also still need

  * smb.conf
  * build options
  * server platform & kernel (seem to have forgotten if you 
    mentioned it before)
  * debug level 10

I think i might have recreated it here so any information you can
provide to confirm will be a big help.
