Description

 

 

 

 

Require Initial

Specifies if the server is allowed to issue

 

Authentication

service to the service principal on behalf of a

 

 

user principal using a previously obtained

 

 

TGT.

 

 

If you set this attribute for the service

 

 

principal, a user principal must

 

 

authenticate to the server again, to obtain a

 

 

ticket for that service. For example, the

 

 

Change Password service requires that a

 

 

principal enter a password to receive a

 

 

ticket for the Change Password service. If

 

 

you do not set this attribute, the server

 

 

issues a server ticket based on the TGT that

 

 

it already possesses.

 

 

The Require Initial Authentication

 

 

attribute applies only to service principals.

 

 

If you select this attribute for a principal

 

 

being edited or created, the Allow as Service

 

 

attribute is automatically selected.

 

 

 

 

Set As Password

Specifies if the server is allowed to issue

 

Change Service

initial tickets to this service principal for

 

 

user principals whose passwords have

 

 

expired.
