Better method for authenticating samadmin commands
[Originally JIRA SAMDEV-64]
The current method for authenticating samadmin commands is not very secure and won't work with Kerberos authentication of database accounts.
omniORB supports CORBA over SSL, so one option would be to require this for admin commands. We already have certificate subjects mapping to SAM users in the DB; we would require a new table listing which SAM users are allowed to run admin commands. The DB server would then have to confirm that the provided subject belonged to a user on the permitted list before running commands.
