One thing I do note is that your AD domain ends on .local, which is defined/known as a DNS multicast domain (‘Multicast DNS’ ([http://www.multicastdns.org/](http://www.multicastdns.org/))) and means hosts in a .local domain won’t resolve normally on SLES 10 unless one turns off the mDNS option. As a quick test, can you ping and/or resolve the domain controller by name from the SLES server? In any case, add the ‘mdns off’ option to the /etc/host.conf ## Code: mdns off * * * , and make sure the /etc/nsswitch.conf hosts and network parameters are only is set to look at files and dns, like; ## Code: hosts: files dns networks: files dns * * * …then reboot the SLES server. Then retry the LDAP (re)configuration and see if the error presists. -Willem – Novell Knowledge Partner (voluntary sysop) ## It ain’t anything like Harry Potter.. but you gotta love the magic IT can bring to this world magic31’s Profile: [http://forums.novell.com/member.php?userid=2303](http://forums.novell.com/member.php?userid=2303) View this thread: [http://forums.novell.com/showthread.php?t=449495](http://forums.novell.com/showthread.php?t=449495) ---

Hi I check the nsswitch.conf and its like you say hosts: files dns networks: files dns I have as dns server the AD server, so i can ping and resolve correctly mydomain.local And the other thing is if i make a ldapsearch command i can sucessfully access to the ldap database same thing with the yast ldap browser The problem is just when i use the option “Create Default Configuration Objects” in the yast2 ldap Regards, ## – xebax24 xebax24’s Profile: [http://forums.novell.com/member.php?userid=121132](http://forums.novell.com/member.php?userid=121132) View this thread: [http://forums.novell.com/showthread.php?t=449495](http://forums.novell.com/showthread.php?t=449495)
