apt-get install fails when it first tries to run slapd. The installation aborts, incomplete. Using the debugger, here are the results:

gdb /usr/sbin/openldap

This verion was installed over a previous openldap built against openssl. Gnutls//openlda should not crash the install because it doesn't like the formatting of an option string. Trusty lts

Hi, thanks for the report. This is already a known bug and fixed upstream in newer versions, so marking as a duplicate.
