Authentication and Access Control System

<i>Hi</i>

I have a few questions regarding the SAP UME that I really need answers to.

1. Is the password stored encrypted in the database?

2. Is the password stored in such a way in the db, that it is impossible for the Sys admin to decode it?

3. Is the password one way encrypted. Even the vendor can't decode the password?

4. Can the user be limited to only use certain workstations?

5. Is the SAP UME totally secured from access via third party programs, such as MS Access, MS Excel, MS Notepad ....?
