InfoPath Dev

Hopefully someone know what I'm doing wrong.

 the Error I'm getting is:

The directory property cannot be found in the cache

For Some reason I can't post the Sample Code, I get an error from the InfoPathDev site

baisicly try in to get a group list for a user.

'LDAP querys
'.....
'..... 
arrMemberOf = objGroup.GetEx("member")   ' <---------   This is where the Error is pointing

Any Ideas???

The funny thing is that if I run the code in a stand alone Script it Works without any problems

why not in InfoPath
