        There's no tooling specifically for doing this, but the plugin
        supports
        it.  In order to get it to use a fixed port, you'll need to
        edit the
        directory server entry for "cn=NIS Server, cn=plugins,
        cn=config" and
        add a "nsslapd-pluginarg0" value which contains the port
        number you'd
        like it to use.

        You can do this either by stopping the directory server,
        editing its
        dse.ldif file directly, and then restarting it, or by editing
        the entry
        "live" using ldapmodify and then restarting the server.  The
        latter
        method (I'm using port 541 here) looks something like this:

         # ldapmodify -x -D "cn=Directory Manager" -W <<- EOF
         dn: cn=NIS Server,cn=plugins,cn=config
         changetype: modify
         replace: nsslapd-pluginarg0
         nsslapd-pluginarg0: 541
         -

         EOF
         # ipactl restart

        You'll need to supply the Directory Manager password.  Once
        that's done,
        running "rpcinfo -p" on the server should show that the NIS
        service is
        listening on the desired port.

        HTH,

    Nalin,

    Thanks a lot for the tip. It definitely looks like this put me on
    the right path though I am not quite there yet.

    Doing what you suggested did not quite work. For one thing, the
    right cn is "NIS", not "NIS Server". Another thing is, it does not
    look like the LDIF files in question have the nsslapd-pluginarg0
    parameter - or are happy with it being added.
    You have to shutdown the directory server first
    service dirsrv stop
    or
    systemctl stop dirsrv.target


Rich,

I even went as far as rebooting the whole machine - even that did not
seem to make a difference.

Boris.

Strange, it is NIS Server on my install too. Can you show the output of your entry?

This worked for me:

# ldapmodify -x -D 'cn=directory manager' -w secretpassword
dn: cn=NIS Server,cn=plugins,cn=config
changetype: modify
add: nsslapd-pluginarg0
nsslapd-pluginarg0: 541

modifying entry "cn=NIS Server,cn=plugins,cn=config"
