[psp] Escaping search filters?

I think I ran across an issue where the PSP is not escaping search filters when trying to query LDAP. What I'm seeing is if you for instance update the description of a group in Grouper (and have the PSP configured to update LDAP with that via the change log) with a value that contains an open parenthesis, such as "test (test", then you get the following exception:

Also, the root cause of the error isn't being logged, which may be another issue..
