Pre-authentication information was invalid (24)

Hi

I'm getting a Pre-authentication error for one user, all other users the authentication works well (60 others). So could anyone hazzard a guess as to why I get this problem just for this one user?

I've looked at reasons for this error:

a) bad password

b) time skew

c) useKeyTab option (I am not using this)

and I can confirm the password is correct, all users are authenticated through the same java code residing on my solaris machine, so time skew isn't an issue. ANd I do not use the keytab opton.....

Any heroic suggestions welcomed.

...and there have been multiple fixes to jgss code between 5_06 and 5_09 so no wonder it works now.But how random a problem I was experiencing, untrue!Tom

Such an error is seen when additional pre-authentication is required.

Lastest Kerberos specification defines new pre-authentication mechanisms,

that indicate a requirement for additional pre-authentication.

Support for the new pre-authentication mechanisms is now available from

Java SE 6, and has been backported to Java SE 5.0 Update 8.

That's the reason it all works now when you upgraded to J2SE 5.0 Update 9 :-)
