Samba 3.5.2 was built under Solaris 10 sparc.  I compiled using gcc and the latest libs for ldap/kerberos/etc from blastwave (stuff got horribly broken when I tried using Sun Studio to compile even though the compile succeeded).

Either way, here is some excerpts from the winbind log. Any help with figuring out what is going on would be appreciated.  This stuff is *NOT* broken under 3.4.7. 

[2010/05/04 02:34:44.540298,  2] winbindd/winbindd_util.c:221(add_trusted_domain)
  Added domain BUILTIN  S-1-5-32
[2010/05/04 02:34:44.541323,  2] winbindd/winbindd_util.c:221(add_trusted_domain)
  Added domain CNS3  S-1-5-21-3477661738-17456881-3314112931
[2010/05/04 02:34:44.542353,  2] winbindd/winbindd_util.c:221(add_trusted_domain)
  Added domain ENVMASTER ENV.GOV.AB.CA S-1-5-21-2022982267-965564276-250757269

Winbind has no problems adding these domains to the trusted domain list. However I notice later on in the log it gets the following:

[2010/05/04 02:34:44.846255,  3] lib/util_sid.c:228(string_to_sid)
  string_to_sid: Sid (NULL SID) does not start with 'S-'.
[2010/05/04 02:34:44.846465,  0] winbindd/winbindd_util.c:325(trustdom_recv)
  Got invalid trustdom response

and than proceeds to loop and tries to list the trusted domains again (it does this several times). It seems to me like the directory is returning a null SID in attempts to resolve any of the trusted domains, however it did not do this before under 3.4.7. Any input into this issue would be appreciated, thanks!
