Per-module access to users with svn+ssh ?

Hi, i would like to limit access on modules (dirs) to different group of
people. Currenly we are providing svn+ssh (on fsfs svn) access, where
the ssh server uses LDAP to get its auth information.

How can we define permissions? In CVS it was quite easy as files were
files and normal unix permissions applied.

PS: it such permissions can only be granted with another access method,
please let me know.
