I was first introduced to F5 technology in 2018. Coming from a primarily Layer 3 & 4 background, it was a mind blowing experience and love at first sight. Since then, I've been following the DevCentral community, initially just reading with a business account. Now, feeling more confident in my knowledge, I'm eager to contribute and help others solve challenges, just like others have helped me. Of course, the learning never stops, I'm still growing every day thanks to the insights shared by more experienced and smarter members of the community.

    This is actually intended to enable user credential-based SSO within SAML SP policies — which, by default, is a feature of APM.

    LTM, on the other hand, doesn't provide access management capabilities, so I'm not sure how such an approach would work in that context.

    Did you have a specific use case or scenario in mind?
