How to add user into group and create new contact with user data?

[rakshazi]

Hello!
This is not issue as "bug", its a question.
I use LDAP user backend, but need to extend it's functionality.
I need to create nextcloud app which can do following things after user registration via LDAP (based on user hook):

1. Add that user into group "Users"
2. Create new contact with user information from LDAP into addressbook "Users"

I already found how to get basic user info, but I don't know how to get info from ldap user data.

Please, help me with following questions:

1. How to get full user info from LDAP (needed all fields)?
2. How to add user into nextcloud group?
3. How to create new contact with that info?

Thank you!
