I config 7 servers on HQ & branch office, 5/7 were placed on
branches,which has only his partition replica,not own [root]partition

some time my branch users told me that they could not log in . I check I
could not login remote server by SSH / telnet or VNC. local user help me
to restart server.

When server started successful, I logon it by SSH , and check
/var/log/messages and /var/log/warn....many message told me some messages

/usr/sbin/namcd[30999]:Error [80] in LDAP search for
/usr/sbin/namcd[30999]:write_errToSock: Write error to socket ,error 32

I had check ndsd is to fine and full sync.
How could I fix the issue ???
