enable native-tls to verify cerver CA & patch user/pwd login responce parsing

[alexshagiev]

it appears the feature for native-tls already present in the cargo.toml but the code does not allow enabling this feature. I understand that using Mutual TLS is still not possible but at least this way it is possible to use OS cert store to use reqwest's native-tls

@jmgilman , what do you think can this be merged & released to crates.io?

Thanks for submitting the PR !

For the same reasons described https://github.com/seanmonstar/reqwest/issues/2025issuecomment-2913873836 I'm thinking of ditching the native-tls feature. Now, we are sure it's not used, as you've shown it's currently broken.

Now, we use reqwest with the webpki feature, which doesn't load the OS cert store. If instead we used rustls-platform-verifier, which also uses the OS cert store, would it satisfy your needs ?

Note: rustls-platform-verifier is not natively supported by reqwest yet but there is a workaround
