This was a pending change to: - Use the same tagline, copyright and license notice across files. - Remove authors' contacts that are no longer valid (due to affiliation changes). - Update repository location. - Update license file with missing licenses (althought those were already in source files). This doesn't include any change on the source code, nor any change on current copyright or licenses. Just formatting and phrasing to make our and distro's maintainers life easier.

# Description:
|
|
# This script will add a computer account to the domain and set its password.
|
|
# Allows to use SAMR over SMB (this way is used by modern Windows computer when
|
|
# adding machines through the GUI) and LDAPS.
|
|
# Plain LDAP is not supported, as it doesn't allow setting the password.

|
|
# ToDo:
|
|
# [ ]: Complete the process of joining a client computer to a domain via the SAMR protocol
