我在 serverfault 上发布了这个问题,但我没有答案,所以我在这里尝试...是否可以混合使用 mod_ssl 和 mod_auth_ldap 以便使用客户端证书和使用 mod_auth_ldap 的授权完成身份验证(需要 ldap-group)?如果是这样,你能给我一些指导吗?提前致谢
I posted this question on serverfault, but I had no answer, so I'm trying here... Is it possible to mix mod_ssl and mod_auth_ldap so that the authentication is done with the client certificate and authorizations with mod_auth_ldap (Require ldap-group)? If so, can you give me some pointer? Thanks in advance
推荐答案好的,对于那些感兴趣的人,apache 要求存在 AuthType 指令并通过某些模块验证用户名.
OK, for those interested, apache requires the presence of an AuthType directive and the validation of the username by some module.
所以我写了一个很短的模块,它接受 AuthType Any 并接受任何用户名.
So I have written a very short module that accepts AuthType Any and accepts any username.
配置如下:
<Location /slaptest> Allow from all SSLVerifyClient require SSLVerifyDepth 1 SSLUserName SSL_CLIENT_S_DN_CN AuthType Any AuthAnyAuthoritative on AuthLDAPURL "ldaps://vldap-rectech/ou=XXX,ou=YYY,o=ZZZ?cn" AuthzLDAPAuthoritative on AuthLDAPBindDN "cn=UUU,ou=Users,ou=XXX,ou=YYY,o=ZZZ" AuthLDAPBindPassword "******" AuthLDAPGroupAttributeIsDN on AuthLDAPGroupAttribute member AuthLDAPRemoteUserIsDN off Require valid-user Require ldap-group cn=ADMIN,ou=Groups,ou=XXX,ou=YYY,o=ZZZ </Location>更新:
模块的代码如下所示.它定义了以下指令:
The code of the module is listed below. It defines the following directives:
AuthAnyAuthoritative 开/关
AuthAnyAuthoritative on/off
AuthAnyCheckBasic 开/关
AuthAnyCheckBasic on/off
如果 AuthAnyCheckBasic 开启,模块将检查从证书中获取的用户名是否与 Authorization 标头中的开启匹配.
If AuthAnyCheckBasic is on, the module will check that the username obtained from the certificate matches the on in the Authorization header.
