Subject: [PATCH] pam: fix storing auth types for offline auth
|
|
|
|
Before the recent patches which allow krb5_child to iterate over all
|
|
available authentication methods typically only one method was returned.
|
|
E.g. is Smartcard authentication (pkinit) was possible it was typically
|
|
the first method the in question list and the result of the
|
|
answer_pkinit() function was immediately returned. As a result only the
|
|
Smartcard authentication type was set and a missing password
|
|
authentication type while others were present might have been a
|
|
reasonable indicator for the online state.
|
|
|
|
With the recent patches, all available methods, including password
|
|
authentication if available, are return and a new indicator is needed.
