Chris,
How are your targets setup in each provisioning group?For example...are you also keeping the group of users that will have an unlimeted option under a separate OU?. -, Or, are you assigning an attribute to identify those users and referencing an LDAP query in your Provisiong Group to enable them?
I'd recommend enabling one user for each PG first to assure that each provisioning group is directed to the correct Vault Stores once "Automatic Enablement" has been configured. This will also assure that a specific Vault Store is linked to the correct Provisioning Group.
Once the above has been completed...then i recommend updating your targets in each provisioning group for "Automatic Enablement".
Please let me know on any questions,
Hope this helps!
Thanks,
Dennis
