CentOS - Feb 2011 - nss_ldap: reconnected to LDAP server ldap://127.0.0.1

Hello, I have a problem that I'm really having trouble figuring out.  I 
run CentOS Linux 5.5.  I have three servers.  All have been setup and 
running with LDAP authentication for a couple years with absolutely no 
problems.

Unfortunately a couple weeks ago, we had a power outage.  Ever since, I 
am having continuous problems with authentication to the server.  I see 
in /var/log/messages

nss_ldap: reconnected to LDAP server ldap://127.0.0.1

I did run a yum update that installed an update to ldap, however that 
did not fix the issue.

I have seen a post mentioning changing 'nss_connect_policy persist' to 
'nss_connect_policy oneshot'.  However I don't see this setting in
my
server, and again, the server was working perfectly fine for years 
before the power outage.

I'm really thinking that some file got corrupted and I just need to 
clean it out.  Maybe a cache file somewhere?

Following is ldap.conf file. Any suggestions?

<ldap.conf>
base dc=inside,dc=msi
timelimit 120
bind_timelimit 120
idle_timelimit 3600
nss_initgroups_ignoreusers 
root,ldap,named,avahi,haldaemon,dbus,radvd,tomcat,radiusd,news,mailman
rootbinddn cn=Manager,dc=inside,dc=msi
nss_base_passwd ou=People,dc=inside,dc=msi
nss_base_shadow ou=People,dc=inside,dc=msi
nss_base_group ou=Group,dc=inside,dc=msi
uri ldap://127.0.0.1 ldap://my.domain
ssl no
tls_cacertdir /etc/openldap/cacerts
pam_password md5
</ldap.conf>

Update, using Webmin to restart the server, I see the following:
Stopping slapd: [  OK  ]
Stopping slurpd: [  OK  ]
Checking configuration files for slapd:  bdb_db_open: unclean shutdown 
detected; attempting recovery.
bdb_db_open: Recovery skipped in read-only mode. Run manual recovery if 
errors are encountered.
config file testing succeeded
[  OK  ]
Starting slapd: [  OK  ]
Starting slurpd: [  OK  ]

I've been reading that the recovery is supposed to be automatic. 
Unfortunately it seems to be a read-only mode.

Anyone know why it is read-only mode?

Anyone have a simple tutorial on running 'db_recover' command?
