Stefan Seelmann commented on DIRSTUDIO-1200:
--------------------------------------------
I started to refactor the whole thing. Removing the LdifAttrValLine handling
condition because it's not necessary because the "dummyEntry" already contains
all attributes. The main issue is in "compareAttributeNames" because only one
attribute is tested if it is objectClass or not which is not symmetric.
> LDIF export fails with "Comparison method violates its general contract!"
