adding mail objectClass to schema

["Darouichi, Aziz" <adarouic@post03.curry.edu>]

Hi all,

 

 

I am trying to create  groups within in Openldap-2.4.34  to use for  Gmail Active Directory Synch “GADs”  I formed the ldif file  with following attributes:

 

dn: cn=Google,ou=Group,dc=curry,dc=edu

objectclass: groupOfUniqueNames

cn:

mail:

description:

uniqueMember:

uniqueMember:

 

 

when I try to add  the file I get the following error:    adding new entry "cn=Google,ou=Group,dc=curry,dc=edu"

ldap_add: Object class violation (65)

        additional info: attribute 'mail' not allowed

 

Thanks.
