Description Joe Orton 2002-12-19 11:26:53 UTC
Description of problem:
If mod_authz_ldap is configured a for *any* location, it tries to take over
authentication for *all* locations where auth is required (even if other
locations use AuthUserFile-based authentication).

Version-Release number of selected component (if applicable):
0.19

How reproducible:
always

Steps to Reproduce:
Use a config like:

   <Location /ldap>
      AuthzLDAPServer localhost
      AuthzLDAPUserBase dc=example,dc=com
      AuthzLDAPUserKey uid
      AuthzLDAPUserScope base

      AuthType basic
      AuthName "ldap@example.com"
      require valid-user

   </Location>

   <Location /basic>
	AuthType basic
	AuthUserFile /blah/passwd
	AuthName "basic@example.com"
	require valid-user
   </Location>

Then try and access location /basic/
    
Actual results:
failure to autbenticate regardless of username/password
error_log entries as follows:

[Thu Dec 19 11:20:33 2002] [crit] [client 172.16.18.90] [1650] no ldap connection
[Thu Dec 19 11:20:38 2002] [error] [client 172.16.18.90] [1650] bind as
(null)=joe,(null)/foo failed: 81

Expected results:
authentication in /basic/ based on passwd file contents

Worse yet; mod_authz_ldap prevents use of other auth mechanisms simply
if loaded, even if not configured.

A workaround is to put:
    AuthzLDAPAuthoritative off
in the location where non-LDAP authentication is needed.
