pam_get_user
() function returns the name of the
target user, as specified to
pam_start(3). If no user was
specified, nor set using
pam_set_item(3),
pam_get_user
() will prompt for a user name. Either
way, a pointer to the user name is stored in the location pointed to by the
user argument, and the corresponding PAM item is
updated.
The prompt argument specifies a prompt to
use if no user name is cached. If it is NULL
, the
PAM_USER_PROMPT
item will be used. If that item is
also NULL
, a hardcoded default prompt will be used.
Additionally, when pam_get_user
() is called from a
service module, the prompt may be affected by module options as described
below. The prompt is then expanded using
openpam_subst(3) before
it is passed to the conversation function.
pam_get_user
() will
recognize the following module options:
user_prompt
PAM_USER_PROMPT
item.pam_get_user
() function returns one of the following
values:
PAM_SUCCESS
]PAM_BAD_ITEM
]PAM_BUF_ERR
