We use it extensively (in our current 2.3.x murder and soon in 2.4) for
controlling access to shared folders.

In addition we use ldap/pts as a general purpose authorization service
for our Cyrus Murder installation; we've got a lot of people in our LDAP
directory and Kerberos KDC, but only a subset of that population get
IMAP service.

We haven't had an issue with non-uniqueness of "cn" for group names as
we use a dedicated search base for groups and our groups have their cn
built into their dn...

We have noticed some weirdness when ptloader is configured to
authenticate to the LDAP server, it appears to want to do a SASL proxy
authz *as* the end user.  This seems unnecessarily complex and it fails
in a non-graceful way in our environment, consequently we've configured
ptloader to do anonymous ldap queries.
