Option to Add Students into the LMS Portal

[oomerwaseem]

Can the Registration Department or e-Learning Centre add Students and Faculty Members into the LMS Portal without going into the Desk Application so that the LMS Portal is one single area used by the users?

If not then how can we make the Desk User to have only the specific roles shown to them when adding the users and assign only the specific roles to which the access is available to be assigned?

Looking forward to a solution to this.
