Multi and Kerberos does not work with a positive LocationMatch
Documentation explains how to chain two modules, for example for Kerberos + LDAP : http://www.lemonldap-ng.org/documentation/latest/authapache
A LocationMatch directive is indicated :
{noformat} <LocationMatch /(index.pl|cas/*|saml/|openidserver/)> {noformat}
but it does not work in my environment. It works only when calling explicitely index.pl, for example : kerberos.example.com/index.pl but when calling with the / suffix : kerberos.example.com/ the matching is not correct.
A solution is to declare that any url except login.pl is matching. For Apache 2.2, it can be done with : {noformat} <LocationMatch ^/(?!login.pl)> {noformat}
Maybe this syntax should replace the existant one in the documentation ?
