How to login to Sybase ASE using OS credentials?
I'm assuming sqlplus is designed to allow password-less DB access under certain scenarios (eg, a custom perl script running under the same scenario doesn't, by default, have password-less access to the Oracle DB) ... ?



SAP(Sybase) ASE does not come with any applications which, by default, allow for password-less access to the dataserver.

Having said that ... it is possible to setup password-less access, eg:


design your own custom app that provides password-less access [will likely have to rely on a password file, or an approved method of external authentication]
configure your environment with one of the approved methods of external authentication [see ASE Security Admin, External Authentication for more details]
