1)For now, recover your database, for example:

db_recover -h /var/lib/ldap

(may be slapd_db_recover in some cases)

Check the permissions on all the files in the directory (chown -R 
ldap:ldap  /var/lib/ldap)

Start the ldap service

2)For the future, either:
a)Upgrade to 2.3 which doesn't/shouldn't need the operations listed below 
(hint: http://anorien.csc.warwick.ac.uk/mirrors/buchan/openldap/ has packages 
which are parallel installable with the original RH packages and affect no 
other aspects of the OS or any packages provided by it)
b)Do some things RH missed out which are necessary on 2.2:
-ensure database recover is run any time that it is likely that slapd has been 
shut down uncleanly. The strategy I prefer is doing database recovery in the 
start() function of the initscript (not restart though).
-ensure the database is checkpointed (run db_checkpoint with appropriate 
options from and as the appropriate user from cron)
