DO NOT REPLY [Bug 48623] New: AuthLDAPURL syntax is not RFC-compliant, prevents common failover scenarios

           Summary: AuthLDAPURL syntax is not RFC-compliant, prevents
                    common failover scenarios
           Product: Apache httpd-2
           Version: 2.2.3
          Platform: All
        OS/Version: All
            Status: NEW
          Severity: major
          Priority: P2
         Component: mod_authz_ldap
        AssignedTo: bugs@httpd.apache.org
        ReportedBy: medievalist@gmail.com


mod_authnz_ldap documentation says the first parameter to the AuthLDAPURL
directive is an RFC2255 LDAP URI (the current relevant RFCs are 4516 and 4510),
but the method which has been used for host failover breaks RFC compliance.

My mod_authnz_ldap, which came bundled with Red Hat Enterprise Linux v5.4 as
part of their httpd-2.2.3-31.el5_4.2 package, requires this for syntax:

transport://host host host host host:port/dn?filter-etc

this is not RFC compliant, you cannot embed multiple hosts like that. This is a
hack that prevents several commonplace LDAP failover usages.

This is the right way to do it:

transport://host:port/dn?filter-etc transport://host:port/dn?filter-etc

For example, in an arbitrarily complex two host failover setup:

AuthLDAPURL
ldap://127.0.0.1:9001/cn=mailboxes,dc=example,dc=edu?mailuid?one?objectclass=mailuser

ldaps://ldap.example.edu/ou=People,dc=example,dc=edu?uid?one?objectclass=posixAccount

(Note, buzilla's probably wrapping that, it should all be on one line.)

Any number of space-separated host specifications should be allowed, although
three will be enough for most real-world use cases.

Since RFC-compliant strings may contain spaces internally, quoting of
individual host specifications must be allowed.
