University hierarchy in drupal 7
We need university coordinator role, we can create it in People &gt; Permissions &gt; Roles.
Next, we create department coordinator. We do it just like in first step.
University coordinator can make a new user and set a role to it. So we create user DC, set the e-mail dc@example.com and set the password loremipsum. Standalone Drupal has not possibility to generate a random password.


Then, to let department coordinator manage the insitute coordinators you should install Administer Users by Role. One problem - this module don't let you to manage content created by the users.
