jaas in jboss

[shan Iyer]

hi,
I am trying to use the kerberos LoginModule for Authentication.

Though I created login configuration file and passed that as one of the arguments for LoginContext(), like:

LoginContext("jaasSample", new TextCallBackHandler);

and my jaas.conf reads as:

JaasSample
{
com.sun.security.auth.module.krb5LginModule required
};

I still get an error message as "Unable to locate logincofiguration"

Please help.
Thanx and regards,
Shankar
