Set Uid Failures

[Graham Allan]

We have a similar problem with 2.0.6 on Compaq Tru64 (previously
Digital) Unix 4.0F. This share is for NT roaming profiles and works
fine with 2.0.5a.

[2000/02/23 00:59:51, 1] smbd/service.c:(535)
  peevish (128.101.220.114) connect to service profiles as user allan (uid=5000,
 gid=5000) (pid 920)
[2000/02/23 00:59:51, 0] lib/util_sec.c:(52)
  Failed to set uid privileges to (0,5000) now set to (5000,5000)
[2000/02/23 00:59:51, 0] lib/util.c:(2456)
  PANIC: failed to set uid

util_sec.c does appear much changed from 2.0.5a but I don't know the
cause of the problem. I have too many variables which have changed
since building 2.0.5a to be sure of anything (new OS version, patches,
C compiler...). I can only guess it is the call to unbecome_user() in
smbd/service.c which is failing. It is almost behaving as if we have a
trapdoor uid system (as I understand it), despite never being a problem
in previous Samba versions.
