Just had the same thing happen to me.

Worked around it by doing:

# yum downgrade openldap openldap-servers openldap-clients
# slapcat > my.ldif
# yum update openldap openldap-servers openldap-clients

Remove contents of /var/lib/ldap except DB_CONFIG

# slapadd < my.ldif
# chown ldap:ldap /var/lib/ldap/*
# restorecon -rvF /var/lib/ldap
# service slapd start

It came back up OK.

Looks like the new openldap is built against a different BerkeleyDB than 
the old one.
