[389-users] Error while trying to add Object -> unknown object class "olcSchemaConfig"

I am trying to use LDAP service which is installed in the IPA server to authenticate Guacamole users. Guacamole and LDAP integration specifies that i need to create an additional object called guacConfigGroup.

To accomplish that, i have downloaded the supplied ldif file from and executed ldapadd utility command with the following ldif file:


# ldapadd -h -p 389 -x -D "cn=Directory Manager" -w 'secret' -f guacConfigGroup.ldif


dn: cn=guacConfigGroup,cn=schema,cn=config
objectClass: olcSchemaConfig
cn: guacConfigGroup
olcAttributeTypes: {0}( NAME 'guacConfigProtocol' SYNTAX )
olcAttributeTypes: {1}( NAME 'guacConfigParameter' SYNTAX )
olcObjectClasses: {0}( NAME 'guacConfigGroup' DESC 'Guacamole configuration group' SUP groupOfNames MUST guacConfigProtocol MAY guacConfigParameter )

However, i am getting the following error while trying to add guacConfigGroup object

adding new entry "cn=guacConfigGroup,cn=schema,cn=config"
ldap_add: Object class violation (65)
additional info: unknown object class "olcSchemaConfig"

Any insights will be highly appreciated !
