Elaborate Ruse commented on DIRSERVER-2025:
-------------------------------------------
Hi there,
Thanks for fixing this issue! I am experiencing this issue in 2.0.0-M19
where a request for a sorted search generates this exception in apacheds.log .
Unfortunately, this is causing issues with one of my systems where I can't view
users within an OU having 60 users. Is M20 about to be released or do I need
to do something more drastic like attempt to merge the fix for this and build
from source so my system can browse users in this OU? Thanks!
