Usage: vault auth enable [options] TYPE
Enables a new auth method. An auth method is responsible for authenticating
users or machines and assigning them policies with which they can access
Vault.
Enable the userpass auth method at userpass/:
$ vault auth enable userpass
Enable the LDAP auth method at auth-prod/:
$ vault auth enable -path=auth-prod ldap
Enable a custom auth plugin (after it's registered in the plugin registry):
$ vault auth enable -path=my-auth -plugin-name=my-auth-plugin plugin

$ vault auth enable -path=my-auth my-auth-plugin
