Adding to Nao comments. I tried to reset the user name by calling
pam_set_item(pamh, PAM_USER, NULL) and then call pam_get_user. Then it
asks for the user name with the prompt that we want after we input (say
rama) in the first screen (GDM supplied prompt). In the second screen
(PAM service module supplied prompt) if we enter different user name
(say nao), then password (PAM service module supplied propmt) in the
password screen, it opens sessions for the user name entered in the
first screen (in this case rama).
