Description

We're pointing Directory Studio to an instance of OpenDJ, with valid entries, and none of the entries under a node are displayed.

DNs are in the form of uid=nghZwwtHgxgyvVbTQCYyeY+O4cc=,dc=example,dc=com

It seems that it's the last = sign of the value that is triggering the error.

RFC 4514 doesn't require to escape the "=" character when converting from DN to String representation. 

The error log shows the following stack trace:
