Hello,
I can not change my config.ldif file from the HDB backend to the MDB backend. I have changed the following:

...
When I play back the config and data ldif file after deleting the ldap directories, I get the following error message:
"root@dsme01:/tmp# slapadd -F /etc/ldap/slapd.d -n 1 -l harnet.de.ldif
Database number selected via -n is out of range
Must be in the range 0 to 0 (the number of configured databases)"
Did I change something wrong in my config file above?
Thank you in advance for your support
