What is print_pam_messages() used for ?

[Ralf Hack]

Hi,
	I was investigating why I don't see any warnings from 
pam_ldap indicating the pending expiration of passwords as well as 
for PAM_NEW_AUTHTOK_REQD. Eventually, I found that do_pam_account() 
does not have a conversation function. Also, there is a function 
print_pam_messages (currently empty) which look suspiciously like it 
is ear marked to show just those error messages:

/* auth-pam.c */
void print_pam_messages(void)
{
	/* XXX */
}

	By any chance, is someone working on a patch to show these 
warning messages ?

Thanks.

Ralf.
