Description

 

 

 

 

Lock Principal

Specifies if a principal is active. A locked

 

 

principal still exists in the principal

 

 

database, but it is unable to use or provide

 

 

Kerberos services.

 

 

The Lock Principal attribute applies to both

 

 

user and service principals. If you set this

 

 

attribute for a user principal, tickets cannot

 

 

be issued to the user. If you set this

 

 

attribute for a service principal, tickets are

 

 

not issued to it.

 

 

When a principal exceeds the maximum

 

 

number of failed authentication attempts

 

 

allowed by the password policy file, the Lock

 

 

attribute is set. The default maximum level

 

 

allowed for failed authentication attempts is

 

 

5. If a principal is locked, an administrative

 

 

user must unlock the principal before the

 

 

user authenticates.

 

 

 

 

Allow As Service

Specifies if a principal is allowed to act as a

 

 

service. Set this attribute to allow a

 

 

principal to act as a service (that is, the

 

 

name of the principal is in the server field of

 

 

the service ticket). You must select this

 

 

attribute for any principal that is used as a

 

 

service principal.

 

 

You can apply the Allow As Service

 

 

attribute to all principals, in addition to

 

 

principals that act solely as service

 

 

principals. The attribute is selected by

 

 

default.

 

 

NOTE: User principals must have this

 

 

attribute set when using user-to-user

 

 

authentication.
