Hi,
I'm still struggling with proxycache overlay,that is a first query is 
being answered but a repeated query is not answered, I presume that 
probabely no data is written to cache, although the files sn.bdb and 
telephonenumber.bdb are created.

My search command is
./ldapsearch -H ldapi:// -b ou=adressbuch,o=HDK,c=DE sn=testuser \ 
telephonenumber

As slapd is allways exiting in gdb here my slapd.conf and an excerpt 
from -d3 logging
