According to Platform Support Matrix, we know that CA PAM Client application is the main method of accessing the CA PAM UI.
During the Proof of Concept our Client stated that, in line with internal politics, he wanted to give users from external companies access to the PAM UI exclusively using a Web browser. The Client also stated that competition supports this feature.
We are not able to confirm that in the future it will be possible to rely on this way of accessing the CA PAM (Web browsers will not support NPAPI).
It would be useful for us to know whether the CA is planning to provide Web-browser access to the PAM using other (non NPAPI) technologies in the future.
This is under consideration by product management. Please also take a look at idea https://communities.ca.com/ideas/235731865-hmtl5-and-chrome-support and vote it up.
