I added:

   (date ; gdb -return-child-result -ex run -ex "thread apply all bt full" -ex 
"quit" --args ldapsearch -x -H ldap://ldap/ -b 'dc=intern' uid=admin mail ) < 
/dev/null >> /var/log/nslcd.ldapsearch.boot.log 2>&1 &

But this seems not to give any hints:

where for this boot again 'systemctl status nslcd -l' shows:

   nslcd.service - LSB: LDAP connection daemon

In the log:

   Aug 29 17:04:29 workstation00 ifup[257]: Sending network state change signal

Hm. Any other hints how to pin down the issue?

Best regards,

     Andi
