I did a zimbra ver 5.0.19 from a CentOS 5.3 to the same environment. I had incorporated samba as a domain controller. The migration worked well since all the users data was intact just that the users cant login into the domain. The error displayed is
"[2009/11/19 15:46:21, 0] passdb/pdb_get_set.cdb_get_group_sid(211)
pdb_get_group_sid: Failed to find Unix account for kevin
[2009/11/19 15:46:21, 1] auth/auth_util.c:make_server_info_sam(589)
User kevin in passdb, but getpwnam() fails!
[2009/11/19 15:46:21, 0] auth/auth_sam.c:check_sam_security(353)
check_sam_security: make_server_info_sam() failed with 'NT_STATUS_NO_SUCH_USER"
whereas the user is there. I think i have discovered the error which could be that in the posix tab, where the details of the user are /home/kevin and the bash terminal "/bin/bash", the combo boxes aint there hence its like the fields cant be changed hence from the error am guessing that the user has no account in the unix machine through the /bin/bash protocol...thats wat am thinkng but please HELP!!!
Any help will be highly appreciated
