We had to patch this out of our Cyrus frontends using LDAP as well because 
it iterates instead of retrieves.  We just decided not to support groups in 
the ACL's.

I'd suspect this is exactly whats going on is this code is still there in 
latest Cyrus and it's building the ACL representation.  If you don't care 
about groups you can find, and remove, that code as we did.
