[Bug 294977] Re: not clear how to configure with pam-auth-update

[Brian May]

Hmmm. You appear to have missed the action=store, so the cached
credentials will never be saved in the first place. My understanding the
actions should look something like:

pam_ldap.so use_first_pass
if (authinfo_unavail) {
  pam_ccreds.so action=validate use_first_pass
  pam_ccreds.so action=store
  pam_ccreds.so action=update
} else if (success) {
  pam_ccreds.so action=store
  pam_ccreds.so action=update
} else {
  pam_ccreds.so action=update
}  

Where action=validate will check the password with the cached version,
and action=store will save it on successful authentication.

I am not really certain what this action=update is - probably need to
read the source to find out

Also see <https://help.ubuntu.com/community/PamCcredsHowto>.

Unfortunately I it doesn't seem to install properly either :-(
