Subject: [PATCH 2/7] computer: add create-msa sub-command
|
|
|
436d93 |
|
|
|
436d93 |
Add new sub-command to create a managed service account in AD. This can
|
|
|
436d93 |
be used if LDAP access to AD is needed but the host is already joined to
|
|
|
436d93 |
a different domain.
|
|
|
436d93 |
|
|
|
436d93 |
