I have configured the Incus WebUI to trust a certificate issued by my own CA, and login works fine when using macOS. However, neither Firefox nor Safari on iOS seem to pick up the certificate which I imported as a configuration profile, that being the usual method of adding certs to an iOS device.
Before I spend more time troubleshooting than I already have: Are iOS versions of Safari, Firefox and suchlike even supported by the Incus WebUI? The UI itself does not include related configuration hints, unlike for several other platforms.
My understanding on Incus and certificates while writing How to install and setup the Incus Web UI – Mi blog lah! is that the Incus requires a user certificate (per TLS terminology, trust certificate per Incus terminology). This authenticates the user to the server. Compared to a server certificate which authenticates the server. All certificates on websites that do https are server certificates. Incus authorizes you to connect to the Web UI because you have a user certificate or trust certificate.
@simos The certificate I issued using my own CA appears to be of the proper type. I use a different intermediate CAs for server and client type certificates, so that mixups don’t occur.
Also, the same cert works fine when used in the macOS versions of Safari and Firefox, but not for the iOS browsers. Just in case my OP was insufficiently clear: This is all about one single certificate only, shared across platforms.
