I am able to bind and search AD with ldapsearch, but am unable to get openldap to use it as a backend db.

I am able to search for a user in active directory by using the following:

ldapsearch -v -H ldap://charizard.company.internal -x -b "dc=company,dc=internal" -D "cn=ldap proxy,cn=Users,dc=company,dc=internal" -w 'passwd' -LLL "(sAMAccountName=testuser)"

My slapd.conf looks like: slapd.conf ----------- include /etc/openldap/schema/core.schema include /etc/openldap/schema/cosine.schema include /etc/openldap/schema/inetorgperson.schema include /etc/openldap/schema/nis.schema

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

database ldap suffix "cn=Users,dc=company,dc=internal" rootdn "cn=ldap proxy" uri "ldap://charizard.company.internal"

binddn "cn=ldap proxy,cn=Users,dc=company,dc=internal" bindpw "passwd"

When I try and search on my openldap host, I recive..

[kylec@localhost ~]$ ldapsearch -v -H ldap://localhost -x -b "cn=Users,dc=company,dc=internal" ldap_initialize( ldap://localhost ) filter: (objectclass=*) requesting: All userApplication attributes # extended LDIF # # LDAPv3 # base <cn=Users,dc=company,dc=internal> with scope subtree # filter: (objectclass=*) # requesting: ALL #

In slapd debug log I can see the following...
