UserID's clearing after reboot

[Ryan Ivey <iveymr@gmail.com>]

I'm somewhat new to OpenLdap and not sure what to check here.

After rebooting the server, all UserID's are being cleared and each are 
having to be readded.  Only the uid set in /etc/openldap/slapd.conf 
under the 'access to attr' directive remains and is able to readd the 
other userid's.  This is becoming a problem because more and more 
userid's are being added and each time the server is rebooted we have to 
readd them.   All files in /var/lib/ldap are the same, including the 
id2entry.bdb file, which I've read is the main database file to be 
backed up.  Are the userid's and password's cached somewhere and not 
being written to disk?  Or is there a temporary file being cleared?  I'm 
running ldap on a SLES9 server.

/etc/openldap/slap.d contains the following:

include         /etc/openldap/schema/core.schema
include         /etc/openldap/schema/openldap.schema

schemacheck     on

allow bind_v2 bind_anon_dn

loglevel 256

pidfile         /var/run/slapd/slapd.pid
argsfile       /var/run/slapd/slapd.args

password-hash   {crypt}

           by self auth
           by dn="uid=****,ou=*******,dc=********,dc=com" write

Any help is greatly appreciated.
