each Service Principal Name and exactly one Kerberos User Principal Name
in Active Directory.

information, see SAP Note 1943266.

System Response

Consistency check executed

How to fix this error?

There must be a green indicator in the <ZH>User Principal Uniqueness</>
column for the Service Principal Name selected. This means that each
Service Principal Name is assigned to a single Kerberos User Principal
Name.
Choose the <ZH>Service Principal Name</> tab.
&RESULT&
If your consistency check was successful, you have created a token and
performed a successful token verification. The <ZH>Token Check</> column
displays a green indicator in the row of the respective Service
Principal Name.
If the consistency check was not successful, there is a red indicator.
Check the trace files to find more information.
If both indicators are green, SPNego tokens from Active Directory can be
validated successfully. If the users have been mapped, an SPNego
authentication is possible.
