Kerberos support

CICS® Transaction Server for z/OS® provides support for Kerberos.

CICS supports Kerberos using the external security manager (ESM). The level of support depends on the support provided by the ESM. If your ESM is RACF®, support is based on Kerberos Version 5 and Generic Security Services (GSS).

CICS can verify a Kerberos token by configuring a service provider pipeline or by using the API command VERIFY TOKEN.
