I tried the microsoft spnego lib used in this article with java. I unwrap the spnego token and i pass the byte array to the GSSContext instance acceptSecContext. The error is:
java.lang.IllegalArgumentException: Authentication time of ticket cannot be null
at javax.security.auth.kerberos.KerberosTicket.init(KerberosTicket.java:279)
at javax.security.auth.kerberos.KerberosTicket.(KerberosTicket.java:222)

It looks the context cannot build up its internal representation of the kerberos ticket from the kerberos token. Do you have any ideeas?
Thank you in advance.
