On the one hand, I enjoyed reusing your work.
On the other hand, I think it is more secure to put this kind of data in /etc/pve/tmp/saml than in /tmp/saml/
Then, yes, it is possible to store it on /tmp/saml for example, it is variable data. Nothing is fixed, you are free to do what you want.

Since I'm not a perl specialist, I took what seemed to me the most standard in this language. Have you considered cloning this repos available on GitHub(https://github.com/perl-net-saml2/perl-Net-SAML2)?

Do you have a specific project or library in mind?

Unfortunately, I don't have any knowledge about rust and I'll have a hard time accompanying you on this topic. However, it seems that there are projects on github in opensource, for example https://github.com/njaremko/samael.

I'll tell you again,nothing is fixed, you are free to do what you want.

I test with lemonldapng which is less simple to install and to handle than keycloak.

I remain at your disposal if needed.

Yours sincerely,

Unfortunately, your code depends on code not packaged for Debian. Any idea 
how to replace that (cpanm Net::SAML2)?

Or better, is there a 'rust' implementaion for SAML2? If so, we could make perl bindings
for that and reuse the code with Proxmox Backup Server.

Other ideas?
