Change displayed SSH_USER to logged in user

[prologic]

Feature Description

I think it would be great if Gitea would allow me to customize the display of the SSH_USER in any ssh clone urls displayed.

Why? I've setup an SSH reverse proxy that checks against my Gitea instance to see if there is a valid user with a matching key, before reverse proxying them through to my Gitea instance with the built in git@ user and their public key credentials passed through an agent forwarder.

This way I can add an additional layer of protection in front of my Gitea instance.

But in SSH world, the "username" isn't that important, you could always identify a user by their public key, even in your "SSH reverse proxy"

Do you mind collaborating on this a little bit? I actually do this the other way around where I lookup the presented user to see if it exists in the first place,then match the presented public key.

Hmm, I guess I know what you are doing ......

I could help to propose a demo to show the current user name on the UI for the SSH clone URL, but I am not sure whether it is suitable to merge into Gitea, since it doesn't seem to be a need of a majority.

OK, I think I get some ideas about how to make it neat and merge it into Gitea.

-> Make git clone URL could use current signed-in user #33091

TBH, much more complicated than I thought .... 🤣

Hey just checking, did this get into the GItea 1.23.1 release? 🤔

[prologic]

Looks like it didn't. Just tested this:

[server]
...
SSH_USER = %(DOER_USERNAME)s

No, it is a new feature and only in 1.24

Looks like it didn't. Just tested this:

[server]
...
SSH_USER = %(DOER_USERNAME)s

But it does work, see the document:

SSH_USER = %(DOER_USERNAME)s is wrong. Use SSH_USER = (DOER_USERNAME)

Ahh! Thanks!
