Please ensure that your SAML attributes are configured correctly on both Fortigate (SP) and on Azure (IDP) as they are very easy to misconfigure. To me, that looks like a potential issue during the saml redirection, not an issue with FortiClient.

To get a better grasp of the issue at hand, please run these debugs:

# diag vpn ssl debug-filter src-addr4 x.x.x.x ==> x.x.x.x should be the public ip of the client devicethat is connecting:
# diagnose debug application sslvpn -1

# diag deb app samld -1

# diag deb enable


-> Reproduce issue


To disable the debug:

# diag deb disable

# diag deb reset

I tested it this morning.
Script error appeared with Version 7.0.12 and 7.2.4 on Windows 11 (did work well on Windows 10).
After installation 7.2.3 on Windows 11, everything is working as expected.
