The AuthServer.Admin identity has basically two roles: it is repository=20
of the kaservers master key and it is the service used for=20
administrative operations on the kaserver. The master key is really=20
just used to generate random numbers used by the server, e.g. for=20
generating session keys. An AuthServer.Admin service ticket is used by=20
the kas command when performing its operations. It is a bit of a=20
security flaw to be giving out samples of ciphertext (i.e. admim service =
tickets) using the same key that is used to generate session keys.=20
However, the kaserver changes this key automatically using fairly good=20
sources of random numbers so the risk is very small.
The AuthServer.Admin settings are unlikely to need adjustment. The=20
usual settings affecting the role of any service principal apply as=20
normal, except its password cannot be changed.
