Stefan Seelmann commented on DIRSERVER-1367:
--------------------------------------------
Regarding JNDI: does it produce the same PDU for the following settings?
1. ctls.setReturningAttributes( new String[] { " " } ); // space character
2. ctls.setReturningAttributes( new String[] { "" } ); // empty string
3. ctls.setReturningAttributes( new String[0] ); // empty array
The JNDI API doc only comments the 3rd case.
What PDU is received when running the ldapsearch command?
> Protocol error when requesting attribute with the space character only
