how to sort out 'active directory cannot be found in cache' error

[Gunapriya]

Hi All,

I want to update an attribute in LDAP using VB. when i try to do this using the obj.get property I get the message: 'The active directory property cannot be found in the cache'. How to sort out this error'

Thanks for any help

It would seem to me that you are looking for a property that doesn't exist in LDAP. Have you checked the name of the property? Post the code, and I can look through it.

Compare your code to this or simply use this code as a starting point.
