I'm pleased that SAML 2.0 authentication was added to the latest major release (5.0). The next step is to enable 'Just-In-Time' (JIT) provisioning capability with SAML. I see this was mentioned previously, as part of the original SAML integration request (ZBXNEXT-2663):

The usefulness of this feature makes it a 'must have' for larger organizations - the current manual user account creation method is cumbersome to say the least. It would be good to know if/when this feature will be included so I can decide whether my team needs to take this on as a Dev project. Hoping this will be supported in the next minor release. JIT is supported in the vast majority of the applications we're using on a daily basis and should be considered a standard SAML feature for enterprise environments at this point.
