So, today has been a massive headache... I get in to work. AFP is down; nobody can connect. Restarting the service via Server.app didn't help, so I just rebooted the Xserve completely. Upon boot, LDAP was no longer functional at all. Slapd exits with this error: Code: bdb_db_open: database "cn=authdata": db_open(/var/db/openldap/authdata/id2entry.bdb) failed: Invalid argument (22). I do have a nightly OD backup run by launchd. Unfortunately I was unable to figure out the password to mount the sparseimages that SH script creates. No evidence of the password is in the script, and none of the obvious choices worked. In a desperate attempt to get things going, I decided to try swapping in the id2entry.bdb file from a system clone I made a few months ago. Not much (if anything) has changed in our directory, after all. LDAP is now functional, but the log is filling itself with: Code: SASL [conn=19092] Failure: incorrect digest response I left a voicemail with our Apple server consultant. Things are mostly working aside from our usual issues with passwords being wiped out and managed preferences being ignored. But meanwhile, can anyone tell me what broke / what kind of sins I committed when I "fixed" it?
