[Samba] Trust problems after upgrade from 3.5 to 3.6

[Andrea Venturoli]

Hello.

My setup:
_ one Samba 3.5 domain (XXXXXXXX), with a PDC and a BDC, both running 
FreeBSD;
_ one AD domain (YYYYYYYY) running on two Windows 2003 DCs;
_ bidirectional trust between the two domains.


Everything used to work until I moved the PDC from Samba 3.5 (EOL'ed) to 
3.6; now, users from domain YYYYYYYY cannot access the PDC's shares.


I used to have in smb.conf:
>         idmap backend=ldap:ldap://localhost/
>         idmap alloc backend=ldap
>         idmap alloc config:ldap_url=ldap://localhost
>         idmap alloc config:ldap_base_dn=ou=idmap,dc=xxxxxxxx,dc=xx
>         idmap alloc config:ldap_user_dn=cn=root,dc=xxxxxxxx,dc=xx
>         idmap cache time=120
>         idmap uid=150000-200000
>         idmap gid=150000-200000
>         template shell=/sbin/nologin
>         idmap config XXXXXXXX:backend=nss
>         idmap config XXXXXXXX:range=1000-999999

After the upgrade I changed it this way:
>         idmap config *:backend=ldap
>         idmap config *:range=150000-200000
>         idmap config *:ldap_url=ldap://localhost/
>         idmap config *:ldap_base_dn=ou=idmap,dc=xxxxxxxx,dc=xx
>         idmap config *:ldap_user_dn=cn=root,dc=xxxxxxxx,dc=xx
>         idmap cache time=120
>         template shell=/sbin/nologin
>         idmap config XXXXXXXX:backend=nss
>         idmap config XXXXXXXX:range=1000-999999



I see many errors like the following in log.winbindd-idmap:
> [2013/02/04 19:22:20.847184,  1] winbindd/idmap.c:249(idmap_init_domain)
>   idmap initialization returned NT_STATUS_ACCESS_DENIED

In log.wb-YYYYYYYY
> [2013/02/04 19:20:59.364510,  0] rpc_client/cli_pipe.c:3240(cli_rpc_pipe_open_spnego_ntlmssp)
>   cli_rpc_pipe_bind failed with error NT_STATUS_ACCESS_DENIED



Please, any help is appreciated.
