`xrootd` [specs]( http://xrootd.org/doc/dev45/XRdv310.htm) have a number of things to say about authentication:\r\n\r\n- [kXR_auth](http://xrootd.org/doc/dev45/XRdv310.htm#_Toc464248810)\r\n- [kXR_authmore](http://xrootd.org/doc/dev45/XRdv310.htm#_Toc464248800)\r\n- [Authentication & Access Control Configuration Reference](http://xrootd.org/doc/dev47/sec_config.htm#_Toc489606563)\r\n\r\n`xrdsec` support 6 authentication protocols:\r\n\r\n- `host`: authenticates a user by originating host name only,\r\n- `gsi`: authenticates a user using GSI protocol,\r\n- `krb5`: authenticates a user using Kerberos V protocol, and\r\n- `pwd`: authenticates a user using a password-based protocol\r\n- `sss`: authenticates a user using a simple shared secret protocol\r\n- `unix`: authenticates using the Unix login name and group name\r\n\r\nFor kerberos, we might use:\r\n- https://github.com/jcmturner/gokrb5\r\n\r\nFor GSI, something on top of [crypto/x509](https://godoc.org/crypto/x509)+[crypto/tls](https://godoc.org/crypto/tls) *might* be used/developed.\r\nCurrent
