Hi all,

I am trying to see if I can write a servlet filter to do transparent single sign-on using Kerberos authentication ticket; however, this is over my head

I get the following error:
GSSException: No valid credentials provided (Mechanism level: Failed to find any Kerberos Key)

I am not sure if my code is being able to read the keytab or even if I am doing this correct . I appreciate any help.

Hello Chup,

Please use proper [code] tags.

Do krb5.conf and sa.conf have proper format?

I think I have the proper keytab and krb5 configuration since I can use kinit and get ticket from the kdc.



krb5.conf

Here's an open source project http://spnego.sourceforge.net with documentation, examples and a tutorial. It does exactly what you are trying to do
