I have set up LDAP integration and have it working with both Static and Dynamic groups. However, we would like to us Dynamic groups but recieve a couple of errors which are making us question its stability.

On the Administration->Manage Groups page we get the following java error:
org.apache.velocity.exception.MethodInvocationException: Invocation of method 'getMemberNames' in class $Proxy16 threw exception class java.lang.StackOverflowError : null
