Testing Active Directory generated keytab by authentication (4279872)

Is there any way to test a keytab generated on Windows machines using the tools from Authentication Services?

To validate a pregenerated keytab with vastool you run the following command. Please make sure the keytab is copied and available on the Unix system. Replace <username> with the username the keytab was generated for.

$ /opt/quest/bin/vastool -u <username> -k /path/to/keytab.file auth

You should get a response similar to the following:

testuser@UNIX.COM was successfully authenticated to MACHINE$@UNIX.COM
