When I try to set the preferredDeliveryMethod 
attribute to "any" the GQ give responds with:

Error modifying entry 'o=FOO,cn=Billing,dc=president,dc=eu,dc=org': Invalid
syntax
Additional error: (null)

I found out that the ldapSyntaxes 1.3.6.1.4.1.1466.115.121.1.14 (Delivery
Method) is not shown in GQ. It seems that every ldapSyntaxes without a Validate
function has this problem. The following  quick hack solves the problem, but it
is not a final solution:
