[SSSD] [PATCHES] Add pam_pwd_expiration_warning config option

[Sumit Bose]

Hi,

another new option, this time it is pam_pwd_expiration_warning the
number of days a warning should be displayed before the password
expires.

While writing this patch I realized that it might not be a good idea to
set pam_verbosity to 0 (no message at all) if confdb_get_int() fails.
The second patch sets it to DEFAULT_PAM_VERBOSITY.

bye,
Sumit
