git-http-backend 和 LDAP 身份验证，推送错误：请求的 URL 返回错误：401 需要授权

git-http-backend 和 LDAP 身份验证，推送错误：请求的 URL 返回错误：401 需要授权

我的设置

  • 操作系统：debian
  • git：v 1.7.10
  • apache（启用了 suexec 模式）配置了 git-http-backend 和 LDAP 授权给 git repos，这适用于克隆操作，但不适用于推送，这就是问题所在。我使用 HTTPS 作为与 git 服务器的通信协议。

这是我的配置：

虚拟主机配置：

<IfModule mod_ssl.c>
<VirtualHost _default_:443>

    DocumentRoot /git/myrepos

    <Directory "/git/myrepos">
    Allow from All
    Options +ExecCGI
    AllowOverride All
    </Directory>

ScriptAlias /git /git/myrepos/bin/suexec-wrapper.sh
SSLEngine on
SSLCertificateFile    /etc/ssl/git.crt
SSLCertificateKeyFile /etc/ssl/git.key

<FilesMatch "\.(cgi|shtml|phtml|php)$">
        SSLOptions +StdEnvVars
    </FilesMatch>
    <Directory /usr/lib/cgi-bin>
        SSLOptions +StdEnvVars
    </Directory>

/git/myrepos/bin/suexec-wrapper.sh：

#!/bin/bash
PATH_INFO=$SCRIPT_URL
GIT_PROJECT_ROOT=/git/myrepos
REMOTE_USER=$REDIRECT_REMOTE_USER
export GIT_HTTP_EXPORT_ALL=true
/usr/lib/git-core/git-http-backend

克隆 repos 工作正常（例如git clone https://192.168.0.1/repo1.git）。它接受 ldap 用户的凭证并克隆 repo。

当推送 repo（例如git push origin master）时，它会要求输入凭证，接受它们，然后抛出错误：

error: Cannot access URL https://192.168.0.1/repo1.git/, return code 22
fatal: git-http-push failed

当以详细模式运行推送时（GIT_CURL_VERBOSE=1 git push origin master），它会要求输入凭证、接受它们并且（输出尾部）：

* STATE: DO => DO_DONE handle 0x1cdd270; (connection #0)
* STATE: DO_DONE => WAITPERFORM handle 0x1cdd270; (connection #0)
* STATE: WAITPERFORM => PERFORM handle 0x1cdd270; (connection #0)
* additional stuff not fine transfer.c:1037: 0 0
* The requested URL returned error: 401
* Closing connection #0
* Expire cleared
error: Cannot access URL https://192.168.0.1/repo1.git/, return code 22
fatal: git-http-push failed
  • 我是否正确配置了 apache git-http-backend (带有包装脚本？)？
  • 哪些因素可能导致推送操作出现问题？
  • 如何更详细地调试它？

非常感谢您的任何建议！

经过多次尝试，我找到了解决方案。问题在于 git-http-backend 的 VirtualHost 配置不正确。

这是我的工作配置：

<IfModule mod_ssl.c>
<VirtualHost _default_:443>

        DocumentRoot /git/myrepos

        SetEnv GIT_PROJECT_ROOT /git/myrepos
        SetEnv GIT_HTTP_EXPORT_ALL
        ScriptAlias /myrepos/ /usr/lib/git-core/git-http-backend
        AliasMatch ^/myrepos/(.*/objects/[0-9a-f]{2}/[0-9a-f]{38})$ /git/myrepos/$1
        AliasMatch ^/repos/(.*/objects/pack/pack-[0-9a-f]{40}.(pack|idx))$ /git/myrepos/$1

        ScriptAliasMatch "(?x)^/(.*/(HEAD | info/refs | objects/(info/[^/]+ | [0-9a-f]{2}/[0-9a-f]{38} | pack/pack-[0-9a-f]{40}\.(pack|idx)) | git-(upload|receive)-pack))$" /usr/lib/git-core/git-http-backend/$1

        <Directory "/usr/lib/git-core/">
        Options +ExecCGI
        Allow From All
        </Directory>

        ScriptAlias /cgi-bin/ /usr/lib/cgi-bin/
        <Directory "/usr/lib/cgi-bin">
                AllowOverride None
                Options +ExecCGI -MultiViews +SymLinksIfOwnerMatch
                Order allow,deny
                Allow from all
        </Directory>

        ErrorLog ${APACHE_LOG_DIR}/error.log
        LogLevel warn
        CustomLog ${APACHE_LOG_DIR}/ssl_access.log combined

        SSLEngine on
        SSLCertificateFile    /etc/ssl/git.crt
        SSLCertificateKeyFile /etc/ssl/git.key

        <FilesMatch "\.(cgi|shtml|phtml|php)$">
                SSLOptions +StdEnvVars
        </FilesMatch>
        <Directory /usr/lib/cgi-bin>
                SSLOptions +StdEnvVars
        </Directory>

        BrowserMatch "MSIE [2-6]" \
                nokeepalive ssl-unclean-shutdown \
                downgrade-1.0 force-response-1.0
        BrowserMatch "MSIE [17-9]" ssl-unclean-shutdown


<Location /repo1.git>
Order deny,allow
Deny from all
Allow from all
AuthName "GIT Authentication"
AuthType Basic
AuthBasicProvider ldap
AuthzLDAPAuthoritative off
AuthLDAPBindDN domain\user
AuthLDAPBindPassword passwd
AuthLDAPURL ldap://ldap.server:389/ou=git,DC=domain?sAMAccountName
Require ldap-group cn=git_repo1,ou=git,dc=domain
</Location>

</VirtualHost>
</IfModule>

现在，所有 git 操作都可以通过 https 和 ldap 授权与 git-http-backend 一起正常运行:)

也许它对某些人有用。
