NS7.1: how can I change the directory of the address book?

Hi!
I wanna share my .mab-file with other useres in my LAN.
But I'm not able to tell NS7 in the user.js to search the
.mab-file in an other directory.

This will only search in the profile path:
user_pref("ldap_2.servers.pab_1.filename", "impab.mab");

I tryed to add a network path like this:
user_pref("ldap_2.servers.pab_1.filename", "h:\\data\impab.mab");

But this does not work?

I have a Linux file server wir Windows clients. I don't want to
install an LDAP-server on my Lunix-machine. I hope there is an
easyer way to share the address books.

Can anybody help?
