Subject: [PATCH 01/23] Remove upper-case only check when looking for the
NetBIOS name
It is a convention to use only upper-case letters for NetBIOS names but
it is not enforced on the AD-side. With the new option to specify a

lower-case letters in the name. To properly determine the name from the
keytab the upper-case check should be dropped,dc=

Subject: [PATCH 17/23] Only update attributes given on the command line
When updating attributes of the LDAP computer object we only want to
update attributes which are related to options given on the command
line. Otherwise a simple call of 'adcli update' to check if the machine
account password needs an update might unexpectedly reset other
attributes as well.

Subject: [PATCH 20/23] join: add all attributes while creating computer object
It is possible to create special accounts which can only join a computer
to a domain but is not allowed to do any further operations which the
computer object. As a result if such an account is used during the join
only the ldapadd operation is permitted but not any later ldapmodify
operation. To create the computer object correctly in this case all
attributes must be added while the object is created and not later.

Subject: [PATCH 22/23] Add add-service-principal and remove-service-principal
options
Currently it is only possible to specific a service name for service
principals but not to set the full service principal. This is e.g.
needed if there is a service running on a host which should be reachable
by a different DNS name as well.
With this patch service principal can be added and removed by specifying
the full name.
