IBM directory server - how to restrict AIX client access to read-only

Hello all,

I am using IBM Directory Server (as a part of AIX7 extension pack) in an AIX environment.
To set up the server I use command:
mksecldap -s -a cn=admin -p PWD -S RFC2307AIX -d o=COMPANY -u NONE

Then, to set up IDS clients I use the following (I have 2 mutually replicating servers aixldapsrv1 and aixldapsrv2) :
mksecldap -c -h aixldapsrv1,aixldapsrv2 -a cn=admin -p PWD

Also, I do necessary changes in /etc/security/user and other files to make the rsh/rlogin/ssh authentication to check AIX user/password against LDAP content.
Things work smoothly at this point.

However, any user on a host which is an LDAP client being logged in as "root", can remove, change, create users in the LDAP "domain".
I would like to restrict this capability to a root user logged to a specific host, or specific hosts (not all hosts that are LDAP clients).

I thought maybe there exist some way of establishing a dedicated "read-only" pseudo-administrator user with the dn like "cn=roadmin", and thus the LDAP client initialization would look like:
mksecldap -c -h aixldapsrv1,aixldapsrv2 -a cn=roadmin -p PWD

But how to create such a readonly admin on the LDAP server? Is it possible at all or I should be looking for the solution in some other place?

any suggestion is very much appreciated!

VOLSERLOG(5)							AFS File Reference						      VOLSERLOG(5)

NAME
VolserLog - Traces Volume Server operations DESCRIPTION
The VolserLog file records a trace of Volume Server (volserver process) operations on the local machine and describes any error conditions it encounters. If the VolserLog file does not already exist in the /var/log/openafs directory when the Volume Server starts, the server process creates it and writes initial start-up messages to it. If there is an existing file, the Volume Server renames it to VolserLog.old, overwriting the existing VolserLog.old file if it exists. The file is in ASCII format. Administrators listed in the /etc/openafs/server/UserList file can use the bos getlog command to display its contents. Alternatively, log onto the file server machine and use a text editor or a file display command such as the UNIX cat command. By default, the mode bits on the VolserLog file grant the required "r" (read) permission to all users. The Volume Server records operations only as it completes them, and so cannot recover from failures by reviewing the file. The log contents are useful for administrative evaluation of process failures and other problems. SEE ALSO
