Stefan Seelmann commented on DIRSTUDIO-1172:
--------------------------------------------
In the test I put both variants:
* escaped + and
* 2 RDNs (just replaced 04cc with email attribute because I was too lazy to
define it)
> Studio doesn't display entries due to Invalid DN exception, but DN is
> compliant with RFC4514.

> Key: DIRSTUDIO-1172
> URL: https://issues.apache.org/jira/browse/DIRSTUDIO-1172
> Project: Directory Studio
> Issue Type: Bug
> Affects Versions: 2.0.0-M13
> Reporter: Ludovic Poitou
> Priority: Major
> Fix For: 2.0.0-M14
>
>
> 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:
> {noformat}
