Network user login one one computer broken others work?

I have one computer that all of a sudden stopped allowing any logins from Network users. Everything has been working fine for months. No changes to server except a power cycle. Local users fine. Network users no logins. Login window shakes. Portable home directory users can login only if not connected to network. I have tried everything I could find to fix it short of wiping the hard drive and reinstalling. I remember having this problem once before and deleting the DirectorySevices prefs and redoing the LDAP3 server setup in Directory access fixed it then but not now. I would appreciate some advice of where to look to find out why this machine is so recalcitrant. Other machines on the network do not have the problem, networks users can login just fine. Client OSX 10.4.10 Mac PB G4 17 Server OSX 10.4.10 Server OD Master Network users show up in the login window What I tried: Deleted contents of /library/preferences/DirectoryService Deleted contents of /library/managed preferences Removed LDAP3 server entry in /Applications/Utilities/Directory Access Using /applications/utilities/netinfo manager Deleted /mcx_cache Deleted /config/mcx_cache sudo /system/library/coreservices/mcxd.app/contents/resources/mcxcacher -F Password: DirtyCache(1) == -14136 sudo rm /Library/Caches/com.apple.LaunchServices*.csstore Deleted /Library/Preferences/com.apple.MCX.plist Restarted No network users show up in login window Setup LDAP3 server in directory access with blank binding Restarted Now network users show up in login window but still can't login I think its a kerberos problem but nothing looks wrong. The edu.mit.kerberos file on the bad computer looks ok. I deleted it and it was recreated. I did a kadmin listprincs on the server and all the users show up. Since I can login from other computers I suspect something wrong with the bad computer not the server setup. No changes were made just had a power cycle on the server while the client was connected. Next time tried to authenticate it failed.
