Hi, I could not join the windows machine to the domain even when I added the machine to LDAP database. But in the same windows machine, I can map drive on the Samba server with LDAP based user account. I could not figure out why. Samba 3.0.10 OpenLDAP 2.1.29 Fedora Core 2 Domain: TESTDOMAIN Samba PDC host: enzo windows machine: ajatar The samba log: make_user_info_map: Mapping user [TESTDOMAIN]\[administrator] from workstation [AJATAR] push_sec_ctx(0, 0) : sec_ctx_stack_ndx = 1 push_conn_ctx(0) : conn_ctx_stack_ndx = 0 setting sec ctx (0, 0) - sec_ctx_stack_ndx = 1 NT user token: (NULL) UNIX token of user 0 Primary group is 0 and contains 0 supplementary groups is_trusted_domain: Checking for domain trust with [TESTDOMAIN] secrets_fetch failed! pop_sec_ctx (0, 0) - sec_ctx_stack_ndx = 0 Cache entry with key = TDOM/TESTDOMAIN couldn't be found no entry for trusted domain TESTDOMAIN found. Thanks a lot. -- Regards, Steve Zeng Systems Administrator Mainframe Entertainment Inc T: (604) 628-1000 ext 5293
