Errors in syslog

These errors keep generating in the syslog which is quite annoying for monitoring for other errors as these are flooding it. Anyone know how to resolve these? Help appreciated.

 cimservera[12450]: user2netname: unknown nameservice ^I^I^I^I^Ifor publickey info 'ldap'
 Nov 19 13:31:30 server1 sshd[12499]: subsystem request for sftp
Nov 19 13:31:43 server1 sshd[12502]: user2netname: unknown nameservice ^I^I^I^I^Ifor publickey info 'ldap'

Please post the publickey: entry in your /etc/nsswitch.conf!

This is the entry in nsswitch.conf

publickey: ldap [NOTFOUND=return] files

It looks like the publickey (or publickey.byname) table in the LDAP has got a wrong entry.
But I don't know much about HP-UX ldap - don't even find "ldaplist" that can dump ldap tables.

Do you use ldap at all?

ps -ef | grep ldap

Do you have a /etc/opt/ldapux/client_admin.conf ?

What would be the easiest way to fix this? Not really familiar with ldap atal.

Definitely use ldap..
server:/etc/opt/ldapux # ps -ef | grep ldap
root 876 1 0 18:09:45 ? 0:02 /opt/ldapux/bin/ldapclientd
root 12016 9090 1 15:53:55 pts/0 0:00 grep ldap

I have
ldapux_client.conf

ldapclientd.conf
