PHP 8.1 replaces some kind of resources by built-in class instances.
As is_resource() is always used to test for failures, replace calls by
simple Boolean checks.
PHP 8 deprecates the ability to have
function whatever($arg1, $arg2='something', $arg3)
This commit reorders arguments of functions set_cached_item() and
draw_jpeg_photo() to meet this new requirement.
Adds configuration for TLS client certificates to secure TLS connection
(requires PHP 7.1+ to use).
Updates use of ldap_set_option to report errors if settings fail.
Modifies connection logic to fail if connection preparation fails
(eg. to avoid connections over insecure links if requested TLS fails).
Adds a new sasl mech 'plain' which converts all simple authentication
methods to SASL PLAIN. NOTE: doesn't use auth_type 'sasl' as
credentials may come from login form, stored in cookies etc...
Implemented a 'sasl' auth_type for better control over authentication
flow specific to SASL.
Implemented 'sasl_dn_regex' and 'sasl_dn_replacement' config variables
for mapping from a SASL authentication ID to a bind DN, a necessary step
when using GSSAPI/Kerberos where there is no explicit bind DN provided.
Fixed setting of Kerberos credentials cache location in environment
variable. The location is derived from either an already set
environement variable or the SERVER variable set by the Apache
mod_auth_kerb module.
