PASSPORT Terminal Emulation Software Provides Single Sign-on for IBM and Unix Hosts

HOUSTON, TX - PASSPORT™ terminal emulation software can now be used to provide a single sign-on implementation for IBM and Unix host systems when used with the v-GO SSO® product from Passlogix®. PASSPORT terminal emulation provides access to IBM zSeries (3270), IBM iSeries (5250) and Unix (Telnet) host systems. The v-GO SSO single sign-on software product from Passlogix provides single sign-on to these host systems as well as client/server, web-based, desktop-based and other types of applications as well.


There are many benefits to using single sign-on with a 3270, 5250 or VT100/VT220 terminal emulator program: %%Increased Productivity – Employees that use computers may be required to have anywhere from 5 to 30 passwords to log into the various computer systems they need to access in order to perform their jobs. In addition, these passwords may expire every 30 days. Managing these passwords is a time intensive task and is a productivity loss for these computer users as well as help desk support personnel.

  • Universal Single Sign-on – Assigning a single userid and password to an employee can provide access not only to multiple host mainframe applications, but can also provide access to a web portal, web applications, client/server applications, desktop applications, dial-up and VPN applications as well as others. Web single sign-on is an important benefit.

  • Security - Several authentication options including LDAP, PKI and strong authentication are provided by the v-GO SSO product. In addition, PASSPORT terminal emulation provides SSL data encryption for terminal emulation sessions. Health care providers are now required to secure privacy under HIPAA health care regulations. Many financial institutions are required to protect customer information under the Graham Leach Bliley Act (GLBA). These security regulations can be implemented using PASSPORT terminal emulation with v-GO SSO single sign-on.
