I will need some more information to be able to help with this.

Can you share a slapd configuration that reproduces the issue? (If you 
send your own config, make sure to redact any passwords or credentials, 
including any embedded in base64-encoded fields.) Especially relevant 
would be the database backend, ACLs, and any overlays.

Can you reproduce the issue using ldappasswd(1) to change the password?

You mentioned signal 6, so I assume slapd is hitting an assertion 
failure. Do you have a record of the assertion message, if there was 
one? Can you obtain and share a backtrace (with debug symbols) or core 
dump?

thanks,
Ryan
