I've looked at numerous examples but haven't been able to get my head
around this.

We have added some boolean Auxiliary attributes such as BTROffice and
NOOfice to the main eDir tree. Need to put all the users with these
attributes set into a group in the vault. Would like to not extend the
vault tree, but instead have IDM leaving our main tree interpret that
this value is changing to true and create a group by same name as the
attribute (if it doesn't exist) in the vault an place the users into it.

Suggestions?

thanks for all the help.
