Hi All.
I have a SAMBA PDC that uses LDAP as its back end.
The OS, is UBUNTU 6.10 Server.
SAMBA Version is 3.022
The problem is, when a client logs onto the Domain, he presses
Control+Alt+Del, and chooses Change Password.
He types in the old password, then the new one, and confirms this.
When he clicks on OK, it thinks for a bit (about 30 seconds) and then says:
"The system cannot change your password now because the domain
RIVONINGO.HIVSA is not available"
This used to work before, and works fine on another server, with the
identical settings.
The log file for the computer says:
[2007/11/27 16:00:11, 0] passdb/pdb_ldap.c:ldapsam_search_one_group(2171)
ldapsam_search_one_group: Problem during the LDAP search: LDAP error:
(No such object)
or sometimes
Unable to open new log file /var/log/samba/log.computername: Permission
denied
My smb.conf looks like this:
[global]
# workgroup = NT-Domain-Name or Workgroup-Name
workgroup = RIVONINGO.HIVSA
netbios name = SOUL-CALIBUR
# server string is the equivalent of the NT Description field
server string = PHRU Domain Control
# This option is important for security. It allows you to restrict
# connections to machines which are on your local network. The
# following example restricts access to two C class networks and
# the "loopback" interface. For more examples of the syntax see
# the smb.conf man page

All hells gonna break loose in 10 days time!
