Using OS_Authentication in cron jobs

I'm looking into using os_authentication for the purposes of running cron jobs which run a sql script through sqlplus. When the appropriate user invokes the shell script from the unix command prompt, the script runs to completion with no errors. However, when the same shell is invoked by the cron facility, I receive an invalid username/password message. Any ideas as to the possible problem? Has anyone implemented a similar setup?

Thanks for any help...
