A Samba Server was configured to join a Windows Domain named DOMAIN1. Due to Domain trusts established in the the Windows Domains there were trusts such as the following present.
DOMAIN1 <-> DOMAIN2 <-> Domain3, where a two-way trust exists between DOMAIN1 and DOMAIN2, and between DOMAIN2 and DOMAIN3, but not directly between DOMAIN1 and DOMAIN3.
This is defined as transitive trusts in Windows Domain terminology.
A Windows Domain user that was a member of DOMAIN3 attempted to access a share authentication would fail and access to the share was denied.
The Samba log for that client name would record messages such as the following:
[2013/06/21 11:52:56.822258, 3] ../libcli/auth/ntlmssp_server.c:348(ntlmssp_server_preauth)
Got user=[USER] domain=[DOMAIN3] workstation=[HOSTNAME] len1=24 len2=264
[2013/06/21 11:52:56.822379, 5] auth/auth_util.c:110(make_user_info_map)
Mapping user [DOMAIN3]\[USER] from workstation [HOSTNAME]
[2013/06/21 11:52:56.822485, 5] libsmb/trustdom_cache.c:160(trustdom_cache_fetch)
no entry for trusted domain DOMAIN3 found.
[2013/06/21 11:52:56.822544, 5] auth/auth_util.c:131(make_user_info_map)
Mapped domain from [DOMAIN3] to [DOAMIN2] for user [USER] from workstation [HOSTNAME]
[2013/06/21 11:52:56.822609, 5] auth/user_info.c:59(make_user_info)
attempting to make a user_info for USER (USER)
This share access will be successful when a Windows Domain user accesses the share from a Windows Client with a share mapped from a Windows Server or the user accesses the share from a Sun 7XXX Storage Appliance that utilizes the SMB/CIFS Server functionality instead of Samba Server.
This was the first time that it was being attempted to have Windows Domain users that exist in DOMAIN3 to access shares from the Samba Server that is a member of DOMAIN1.
