Hi, I am running Apache2.2.16 on a Solaris10 server. I am not using SSL. The part of my httpd.conf file is: LoadModule rewrite_module modules/mod_rewrite.so LoadModule authnz_ldap_module modules/mod_authnz_ldap.so LoadModule ldap_module modules/mod_ldap.so <Directory "/usr2/apache2.2.16/testdir"> AuthType Basic AuthBasicProvider ldap AuthName "Directory Users" #AuthUserFile /dev/null AuthLDAPURL ldap://xxx.xxx.com:389/ou=People,ou=intranet,dc=xxxx,dc=com?uid?sub?(objectClass=*) AuthzLDAPAuthoritative Off #Satisfy Any Require valid-user </Directory> The website comes up. But access to http://xxx.xom/testdir prompts for LDAP authentication but returns 500 Internal Server Error on the browser after typing in login/password (no matter login/password is correct or not). The server error logs have no further information.I used openldap-2.4.22-sol10-sparc-local package. I am trying to upgrade from Apache 1.3.28 to Apache 2.2.16. The LDAP authentication works on the same server in Apache 1.3.28. Could anyone please correct me if I am making any mistake in the syntax above? --------------------------------------------------------------------- The official User-To-User support forum of the Apache HTTP Server Project.
