multiple network users not allowed on client machines via ssh

Hello,

I have setup a Mountain LIon Server with network users.

I have three MAC OS X clients accessed by LDAP Server provided network users.

I have problems on client machines when a network user il logged in from the login window and a second user tries to connect using ssh.

It seems that the Home directory export is owned by the first user connected, the one from the login window.

The ssh connected user does not see his home !

Did anybody have this problem solved?

many thanks

Stefano
