Automount and LDAP : attribute mapping ignored

Hello,

We are running several Solaris servers configured on a very old Sun Directory Server. This server is about to die, that's why we're preparing a migration to a new OpenLDAP server.

The new server also deserve Linux systems. This mean we already have an automount objectClass, and thus used the old nis Schema for the Solaris systems.

As explained in the Solaris 10 documentation, we initialized ldapclient with the AttributeMap and ObjectClassMap parameters.

It works fine with ldaplist, but automount seems to ignore the mapping.

Here are a few config files and command outputs :
*LDAP Client configuration*

As you can see in the capture, it sends a filter containing the objectClass=automount and the attribute automountKey (&(objectClass=automount)(automountKey=*)).
