VirtualBox headless authentication

Written by at March 5, 2012

By default, you could choose VRDE authentication as external to authenticate remote display connection request by using PAM. The default PAM service will be login, or you may:

  • Create a new file named /etc/pam.d/vrdpauth
  • In order to use a custom service you must either set the VRDP_AUTH_PAM_SERVICE environment variable (or recompile the library)
  • Sample /etc/pam.d/vrdpauth 
    auth       required     pam_unix.so
account    required     pam_unix.so
