Subscribes this user to the specified database.
Use this method to subscribe the user to additional databases. To unsubscribe the user, use the UnsubscribeDatabase method. To get a list of the databases to which the user belongs, get the collection of Database objects in the SubscribedDatabases property.
When calling SubscribeDatabase :
$UserObject->SubscribeDatabase($DBObject);
the user is subsequently required to execute UpgradeMasterUserInfo in order for the SubscribeDatabase method to have an effect on the user database represented by $DBObject:
$DBObject->UpgradeMasterUserInfo();
VBScript
user.SubscribeDatabase database
Perl
$user->SubscribeDatabase(database);
