Package: libapache2-mod-authnz-pam It would be nice to have support for credentials caching so that PAM stack is not called for each HTTP request when some heavyweight network authentication is used (my situation, I use libpam-sshauth which checks credentials against SSH server).
Apache module mod_authn_socache does this, but other modules must explicitly support that feature. More info: https://httpd.apache.org/docs/2.4/mod/mod_authn_socache.html Module developers should note that their modules must be enabled for cacheing with mod_authn_socache. A single optional API function ap_authn_cache_store is provided to cache credentials a provider has just looked up or generated. Usage examples are available in r957072, in which three authn providers are enabled for cacheing. http://svn.eu.apache.org/viewvc?view=revision&revision=957072
