memberOf overlay

Hi all,

Am trying to get the memberOf overlay attribute working with openLDAP.

I need to authenticate to a Cisco ASA 5510 and set up group mapping policy.

I've been round the houses quite a few times and got pretty close but no Marlboro Light (let alone a cigar).

My slapd.conf looks like this:

# /etc/ldap/slapd.conf

# Schema and objectClass definitions
include         /etc/ldap/schema/core.schema
include         /etc/ldap/schema/cosine.schema
include         /etc/ldap/schema/nis.schema
include         /etc/ldap/schema/inetorgperson.schema
include         /etc/ldap/schema/samba.schema
include         /etc/ldap/schema/misc.schema

moduleload      back_bdb

# end

I've added an LDIF as follows:

dn: cn=vpnusers,ou=Groups,dc=essence
objectclass: groupOfNames
cn: vpnusers
member: userid=chris.alavoine,ou=Users,dc=essence

Which seems to enter ok. 

I'm using phpldapadmin to look at my directory. The new group "vpnusers" shows up ok and if I do a:

ldapsearch -x -b "dc=essence" '(uid=chris.alavoine)' memberOf

I get:

# chris.alavoine, Users, essence
dn: uid=chris.alavoine,ou=Users,dc=essence
memberOf: cn=vpnusers,ou=Groups,dc=essence

Unfortunately, when I try and query this information from the Cisco it's not picking up on the memberOf attribute. I've set up attribute mapping on the Cisco which allows me to convert the memberOf attribute into something readable by the Cisco but it's not getting that far.

I'm using Ubuntu 8.04 and openLDAP 2.4.9

Any help much appreciated.
