I have had some success with prompting for the password (without username) from sudo like this:

Code:
$ cat /usr/local/bin/zenity_passphrase
#!/bin/bash
zenity --password --title="sudo password prompt" --timeout=10
$ export SUDO_ASKPASS=/usr/local/bin/zenity_passphrase
$ sudo -A id
<GUI prompt for password>
uid=0(root) gid=0(root) groups=0(root) context=unconfined_u:unconfined_r:unconfined_t:s0-s0:c0.c1023

pam_tacplus

PAM_TACPLUS(8)						    BSD System Manager's Manual 					    PAM_TACPLUS(8)

NAME

     pam_tacplus -- TACACS+ authentication PAM module

SYNOPSIS

     [service-name] module-type control-flag pam_tacplus [options]

DESCRIPTION

     The pam_tacplus module provides authentication services based upon the TACACS+ protocol for the PAM (Pluggable Authentication Module) frame-
     work.

     The pam_tacplus module accepts these optional parameters:

     use_first_pass  causes pam_tacplus to use a previously entered password instead of prompting for a new one.  If no password has been entered
		     then authentication fails.

     try_first_pass  causes pam_tacplus to use a previously entered password, if one is available.  If no password has been entered, pam_tacplus
		     prompts for one as usual.

     echo_pass	     causes echoing to be left on if pam_tacplus prompts for a password.

     conf=pathname   specifies a non-standard location for the TACACS+ client configuration file (normally located in /etc/tacplus.conf).

     template_user=username
		     specifies a user whose passwd(5) entry will be used as a template to create the session environment if the supplied username
		     does not exist in local password database.  The user will be authenticated with the supplied username and password, but his
		     credentials to the system will be presented as the ones for username, i.e., his login class, home directory, resource limits,
		     etc. will be set to ones defined for username.

		     If this option is omitted, and there is no username in the system databases equal to the supplied one (as determined by call
		     to getpwnam(3)), the authentication will fail.

FILES

     /etc/tacplus.conf	The standard TACACS+ client configuration file for pam_tacplus

SEE ALSO

     passwd(5), tacplus.conf(5), pam(8)

HISTORY

     The pam_tacplus module first appeared in FreeBSD 3.1.
