We are using gidNumbers assigned to groups through the posixGroup AUX Class.

The desire would be to allow the lookup of "Group" field on the user to
be able to look up the Group by gidNumber.

When we try this, the DN lookup control appears to always try a
substring search which always fails as Integer syntax does not support
substring search.

A LDAP trace shows:
16:10:48 5A62CBB0 -1 LDAP: (10.165.131.55:45212)(0x0043:0x63) Search
request:
base: "OU=groups,dc=willeke,dc=com"
scope:0 dereference:0 sizelimit:0 timelimit:0 attrsonly:0
filter: "(&(objectClass=groupOfNames)(gidNumber=10*))"
attribute: "cn"
attribute: "gidNumber"
attribute: "srvprvHideUser"
attribute: "srvprvHideAttributes"
attribute: "modifyTimeStamp"
attribute: "objectClass"
16:10:48 5A62CBB0 -1 LDAP: ldap2NDSSearchFilter: substring match used on
unsupported syntax

We were able to get around this limitation when using the "Directory
Search" option from the main menu by using the "equals" modifier.

Is there a way to do this on the DN lookup control?

Thanks
