acquireServiceCreds	back to summary
public static Credentials acquireServiceCreds(String service, Credentials initCreds) throws KrbException, IOException Acquires credentials for a specified service using initial credential. When the service has a different realm from the initial credential, we do cross-realm authentication - first, we use the current credential to get a cross-realm credential from the local KDC, then use that cross-realm credential to request service credential from the foreigh KDC. Parameters service:String the name of service principal using format components@realm initCreds:Credentials client's initial credential. Returns:Credentials a `Credentials` object. Exceptions KrbException: if an error occurs specific to Kerberos IOException: if an error occurs in reading the credentials cache

public static Credentials acquireServiceCreds(String service, Credentials initCreds) throws KrbException, IOException

When the service has a different realm from the initial credential, we do cross-realm authentication - first, we use the current credential to get a cross-realm credential from the local KDC, then use that cross-realm credential to request service credential from the foreigh KDC.

Parameters

service:String: the name of service principal using format components@realm
initCreds:Credentials: client's initial credential.

Returns:Credentials

a Credentials object.

Exceptions

KrbException:: if an error occurs specific to Kerberos
IOException:: if an error occurs in reading the credentials cache

A value of null will be accepted to indicate that the default path should be searched Returns:Credentials the TGT credentials or null if none were found. If the tgt expired, it is the responsibility of the caller to determine this.
