Error 5015 is an "ERROR_UNKNOWN" so we need to do more research to find
out where something is breaking down. Looking in the logs for (usually)
Apache Tomcat may show more, or else if you suspect something with the
interaction with eDirectory then using ndstrace and tracing LDAP (among
other things) could be useful, as shown below:

set dstrace=nodebug
dstrace +time +tags +ldap
dstrac file on
set dstrace=*r
#recreate error here
dstrace file off
The default ndstrace.log file will be at

Feel free to post the contents of that file here for review.

Good luck.
