I have installed a commercial package on a Red Hat Linux box under the user CDGUnix which is stored in an Active Directory server.

From another Active Directory user I wish to call a program which has a configuration file including the machine, user name (CDGUnix) and password to be used.

When this configuration file points at another machine on which the commercial package is installed all works fine.

If I call it from another user on the same machine however I get a logon failure message from the package. The events written on the Active Directory server are identical to those written when I try to su to that user without having a sudo in front. My user has the power to do anything if preceeded by sudo.

How can I arrange things so that I can internally log on to this other user? Unfortunately I do not know exactly what mechanism is being used by the package to internally logon. I have being studying the sudo documentation but it seems to only deal with running specific executables and not logging into a service.

If its a commercial pkg, I'd start by asking the company that wrote it. You need to understand how the pkg works.
