[BUG] ssh_config multiple IdentityFile not supported

[mlrtime]

In my pillar I have

IdentityFile:
- ~/.ssh/id_rsa
- ~/.ssh/id_ed25519
- ~/.ssh/id_ecdsa

This Renders to:

Host *IdentityFile ~/.ssh/id_rsaIdentityFile ~/.ssh/id_ed25519IdentityFile ~/.ssh/id_ecdsa

It seems that ssh_config does not support multiple IdentityFile

@mlrtime Thanks for the report. Would you mind linking to the upstream OpenSSH documentation, showing us how this feature is supposed to be supported? The fix can then be linked back to the original sources, explaining why the change has been made.

From: https://linux.die.net/man/5/ssh_config

IdentityFile
Specifies a file from which the user's RSA or DSA authentication identity is read. The default is ~/.ssh/identity for protocol version 1, and ~/.ssh/id_rsa and ~/.ssh/id_dsa for protocol version 2. Additionally, any identities represented by the authentication agent will be used for authentication.

The file name may use the tilde syntax to refer to a user's home directory or one of the following escape characters: '%d' (local user's home directory), '%u' (local user name), '%l' (local host name), '%h' (remote host name) or '%r' (remote user name).

It is possible to have multiple identity files specified in configuration files; all these identities will be tried in sequence.

@mlrtime Thanks. Can you put that into an actual example of what should be rendered in the file itself?

IdentityFile ~/.ssh/identity
IdentityFile ~/.ssh/id_rsa
IdentityFile ~/.ssh/id_dsa
