MFA user's RACF ID got suspended using zowe exploer (dev profile is not using API M/L, connection via z/OSMF REST service):
For MFA user, user is leaving the password blank in the dev profile set up.
When trying to use DataSet browser/explorer, it’ll ask for a password. User enters MFA token id, successfully connected to dev, able to browse DataSet using filter.
After a few minutes, the user RACF ID got suspended. Zowe Explorer seems to save the MFA token id that the user entered above (MFA token is only valid for 60 seconds), and does reconnect/reauthenticate behind the scene and not prompting the user for updated MFA Token.
Release : 4.0
Zowe Explorer v2.6.2
Multifactor authentication is only supported when connecting Zowe client components to APIML. The clients do not support MFA directly to a mainframe service.
Zowe API ML provides a single point of access to a defined set of mainframe services. The layer provides API management features such as high-availability, consistent security, and a single sign-on (SSO) and multi-factor authentication (MFA) experience.
