[pmg-devel] [PATCH pmg-api/pwt 0/2] fix #6214: improve OIDC field validation

[Christoph Heiss]

First and foremost, fixes #6214 [0].

The second patch just adds some more validation on the UI side of
things. While not strictly related to #6214, it's a nice touch.

[pmg-devel] [PATCH pmg-api 1/2] auth: oidc: fix pattern for `client-id` and `client-key`

[Christoph Heiss]

Fixes #6214 [0].

As per RFC 6749 Appendix A [1], `client-id` and `client-key` can contain
any printable ascii character, i.e. anything in the (inclusive) range
0x20-0x7E.

Reflect that in the pattern.

[pmg-devel] [PATCH widget-toolkit 2/2] window: AuthEditOpenId: add validation for required fields

[Christoph Heiss]

For the `client-id` and `client-secret` OIDC-specific fields, allow the
format specified in RFC 6749, Appendix A [0].

As per that, the OIDC-specific `client-id` and `client-key` can contain
any printable ascii character, i.e. anything in the (inclusive) range
0x20-0x7E.

For the issuer URL, use our existing URL validation regex, while the
realm name itself must follow authentication realm naming scheme.
