Problems with etc/rasmgr.auth

[Dimitar Misev]

There are several issues with this file:

• it is not documented anywhere
• rasserver does not throw an error if it doesn't have write access to $RMANHOME/etc
• the behavior with the new rasmgr is unintuitive: when you change a rasdaman user (e.g. new password for rasguest), this file gets written to $RMANHOME/etc/rasmgr.auth.713f3f57-bd3b-4211-ada6-bf88b49f81f1 or some similarly random bits appended. To make it effective, it needs to be renamed to $RMANHOME/etc/rasmgr.auth (as I figured out with some guesswork). I think what it should rather do is, make a backup of an existing rasmgr.auth, and then write the new rasmgr.auth.
