我正在尝试查询一个奇怪的LDAP结构,我需要对其进行身份验证。我们的应用程序使用REMOTE_USER变量来确定用户。我无法访问LDAP目录,因此无法查看它的日志。
结构需要我查询树的子部分,这个Perl脚本用来测试LDAP查询(它按预期工作并返回用户列表)来演示。
use Net::LDAP;
use Net::LDAP::Entry;
$ldap = Net::LDAP->new( 'ldapdevel.my.edu.au' ) or die "$@";
$mesg = $ldap->bind( 'uid=binduser,o=my.edu.au', password => 'bindpass' );
if( $mesg->code ) {
die $mesg->error;
}
$mesg = $ldap->search( # perform a search
base => "o=my.edu.au",
filter => "cn=devraj"
);
$mesg->code && die $mesg->error;
foreach $entry ($mesg->entries) {
$entry->dump;
}
我的Apache配置在VirtualHost条目中有以下内容,其目的是模仿Perl脚本中描述的相同查询。
<Location />
AuthType Basic
AuthName "My Application"
AuthBasicProvider ldap
AuthzLDAPAuthoritative off
AuthLDAPBindPassword bindpass
AuthLDAPBindDN "uid=binduser,o=my.edu.au"
AuthLDAPUrl "ldap://ldapdevel.my.edu.au/o=my.edu.au?cn?one"
Require valid-user
</Location>
我还可以确认Apache是否成功绑定到LDAP目录。
Apache错误日志,用于LDAP身份验证的消息,表示URI是/因此Apache正在搜索目录的顶部而不是o = my.edu.au

我意识到问题是AuthLDAPUrl,我的问题是我在AuthLDAPUrl中做错了什么,或者我应该使用另一个指令?
我还尝试将每个参数单独配置为mod_authz_ldap,如下所示:
<Location />
AuthType Basic
AuthName "My LDAP authenticated app"
AuthzLDAPLogLevel debug
AuthBasicProvider ldap
AuthBasicAuthoritative off
AuthzLDAPAuthoritative off
AuthzLDAPBindPassword bindpass
AuthzLDAPBindDN "uid=binduser,o=my.edu.au"
AuthzLDAPMethod ldap
AuthzLDAPServer ldapdevel.my.edu.au
AuthzLDAPUserBase o=my.edu.au
AuthzLDAPUserKey cn
AuthzLDAPUserScope base
AuthLDAPRemoteUserAttribute cn
Require valid-user
</Location>
这实际上有效!但是...... Apache试图以尝试登录的用户绑定,这显然会失败。如果我使用绑定用户凭据登录,则会通过身份验证,错误日志提取:
[Fri Sep 07 14:14:27 2012] [error] [client xxx.xxx.xxx.xxx] [15628] bind as cn=devraj,l=X,ou=Students,o=my.edu.au failed: 49

感谢您的时间。
