There is no way to create the same kind of UPG for an existing user as 
can be done for a new user. The managed entries plugin manages the 
linkage between the user and group and IPA currently doesn't provide a 
way to create a linkage after the fact.

You can create a group with the same gid with : ipa group-add myuser 
--gid <uid-of-user>, but this isn't exactly "private". A private group 
doesn't allow members.

One of the other features of UPG is that when the user is deleted, the 
group is also deleted. This would not happen in the case of manually 
created private groups.
