WebISO Authentication in the SCS Web Environment

WebISO is a mechanism to provide authentication for web-based services. It allows you to use your SCS Kerberos userid and password to verify your identity for web services such as webmail, the Instance Manager or LDAP lookup. When you first connect to a web service that uses WebISO authentication, you will be presented with a login screen. Once you enter your credentials, you will then be directed to the web service.

In addition, WebISO provides the convenience that your identity information is remembered so that you do not need to re-enter it to access other WebISO services (until you close your browser).

SCS Computing Facilities WebISO

The WebISO service (maintained by SCS Computing Facilities) is used by the Instance Manager, SCS Webmail, the Corvid Attribute Lookup page as well as other SCS services. When you connect to a web service protected by the SCS WebISO service, you will see the following login page:

SCS WebISO page

The page clearly identifies itself as being from the SCS WebISO server, and has prompts for your User ID, Password and a selection for either your regular login instance password or /mail instance password.

If you are accessing SCS Webmail from an untrusted host (a Web kiosk, a cluster machine, or other public host, for example), it is highly recommended that you use your Kerberos /mail instance to log in to WebISO. Select the /mail radio button in the Instance field of the WebISO login page and type your /mail instance password into the Password field.

If you are accessing SCS Webmail from a trusted host (your desktop workstation, for example) you may log into WebISO with your standard Kerberos username and password.


Shibbolith is a web authentication system similar in some ways to Pubcookie, though having more features and additional complexity.

More information about Shibboleth, including screenshots is available on our Shibboleth login page.
