Dear list,
Do any of you use the latest(3.0.4) as a Samba PDC(with OpenLDAP) on Linux ?
If yes, have you encountered the following problem ?
The setup is a PDC with an LDAP server running locally which is accessed
directly and through nsswitch/PAM. A member server is providing shares to
clients.
When looking up domain users (wbinfo -u) from a member server(Solaris 8,
OpenLDAP 2.1.25) there are no problems. When looking up users on the PDC and
on the BDC, it fails (Error looking up domain users). The log.winbindd
states problems with socket read errors. When running "wbinfo -m" we only
get "BUILTIN". When running "wbinfo -g" we get:
BUILTIN+System Operators
BUILTIN+Replicators
BUILTIN+Guests
BUILTIN+Power Users
BUILTIN+Print Operators
BUILTIN+Administrators
BUILTIN+Account Operators
BUILTIN+Backup Operators
BUILTIN+Users
The PDC is running Mandrake 9(2.4.19-16mdk, OpenLDAP 2.0.25) and the BDC is
running RedHat 7.3(2.4.18-3, OpenLDAP 2.0.27) and works without problems in
other regards.
Have tried a similar PDC/BDC configuration on Mandrake 10 as well with same
results.
The problem was first discovered in Samba 3.0.2(currently 3.0.4) and
searching the mailing lists does not reveal anything that equals our
situation.
Samba config options are: ./configure -with-acl-support -with-libiconv
Things checked: There are no firewall rules. Different socket options tried.
Custom compiled and vendor compiled binaries tried. LDAP entries commented
out with no affect.
Guess on cause: The LDAP lookup is messing up a socket used for local host
communication.
