[Bug 1414303] [NEW] sudo show predefine PAM prompt with some PAM Modules, no default sudo prompt

 

Public bug reported:

I use libpam-krb5 for authentication, when I use sudo it show this
prompt

Password:

Not the default of sudo

[sudo] password for (user):

But if it's set LANG=C (no locale) with module libpam-krb5 show the
default prompt of sudo.

With the module pam_unix (default of system) work without problems.

Then the problem is in locale support of one of these packages. At check
the source code of two I reached the conclusion.

1. libpam-krb5 not support translations.

2. sudo replaces the PAM prompt if this is "Password:" or translate of
this. But sudo only check "Password:" translated on current language
config (example "Contraseña:" on "es" locale).

This bug not cause "real" problem but it may reveal the authentication
system in use.

This report has attached a (possible) patch of sudo for fix the bug.
