Hope someone can help!

I've got a problem with ldap. Server was running fine until I tried to add an alias and got errors. Figured they were ldap errors. Stopped the server, ran zmfixperms --extended to see if that would help.

Tried to restart the server and get the following error:
Failed to start slapd.  Attempting debug start to determine error.
hdb_db_open: database "": db_open(/opt/zimbra/data/ldap/hdb/db/id2entry.bdb) failed: Invalid argument (22).
backend_startup_one: bi_db_open failed! (22)
bdb_db_close: database "": alock_close failed
I've searched the forums and found some similar issues with older versions...
I'm running:
zmcontrol -v

Release 6.0.1_GA_1816.RHEL5_64_20090911174852 CentOS5_64 FOSS edition
My backups appear to be corrupted so I'm stuck.

I've read the following post: [SOLVED] LDAP / slapd - Database environment corrupt (Issue & Solution)

but can't seem to figure out what steps to take for 6.x version of ldap.


Thank you so much!
