OpenLDAP 2.4.7 Bug?

["Allan E. Johannesen" <aej@WPI.EDU>]

I'm not runing a 2.3 server for comparison, but is this a bug or is it expected
behavior to have this sort of error?

In a program, which had constructed the ** due to a missing first name, it also
was found to break the connection to the server...
