[ovirt-users] Automated users/groups creation and updating them

Hi, I'm trying to find what are the different ways / approaches to automated users/groups creation, based on a LDAP/AD database. This is my first problematic : when a LDAP/AD provider is joined, and a user is created in ovirt from this provider, the user heritates a part of the attributes from this LDAP database. Now if I change one attribute on the LDAP side (for example "first name"), it isn't updated on the ovirt user. Would there be other way to update this information than creating / deleting the user ? My second problematic is what should I use to automate creation of users. It seems possible with : - shell scripting : using ovirt-aaa-jdbc-tool - python SDK - java SDK - rest API Which one of these approaches would be the most simple ? I'm more familiar with shell scripting than other languages. That would be nice to find a way with it. Concerning ovirt-aaa-jdbc-tool, I've heard it was only adding/deleting users from the internal DB, not the others. In that case, is there a way in shell scripting to interact with other profiles than internal ? Is there files somewhere containing users and their informations I could modify ? What would happen if a user is in use and it is modified/deleted at the same time ? I know it makes a lot of questions, but I can't really get started before having those answers.
