svn使用openldap验证apache访问方式

启用svn服务器的sasl验证机制

1、安装cyrus-sasl认证包

# yum install -y *sasl*

# rpm -qa|grep sasl

cyrus-sasl-2.1.23-15.el6_6.2.x86_64

ruby-saslwrapper-0.14-1.el6.x86_64

cyrus-sasl-md5-2.1.23-15.el6_6.2.x86_64

cyrus-sasl-lib-2.1.23-15.el6_6.2.x86_64

cyrus-sasl-devel-2.1.23-15.el6_6.2.x86_64

cyrus-sasl-gssapi-2.1.23-15.el6_6.2.x86_64

saslwrapper-0.14-1.el6.x86_64

cyrus-sasl-sql-2.1.23-15.el6_6.2.x86_64

python-saslwrapper-0.14-1.el6.x86_64

cyrus-sasl-ldap-2.1.23-15.el6_6.2.x86_64

cyrus-sasl-ntlm-2.1.23-15.el6_6.2.x86_64

cyrus-sasl-plain-2.1.23-15.el6_6.2.x86_64

saslwrapper-devel-0.14-1.el6.x86_64





2、修改sasl认证模式为shadow

# cp /etc/sysconfig/saslauthd /etc/sysconfig/saslauthd.bak.$(date +%F%T)

[root@node5 config]# ll /etc/sysconfig/saslauthd*

-rw-r--r-- 1 root root 553 Feb 27  2015 /etc/sysconfig/saslauthd

-rw-r--r-- 1 root root 553 Jul  1 21:14 /etc/sysconfig/saslauthd.bak.

-rw-r--r-- 1 root root 553 Jul  1 21:14 /etc/sysconfig/saslauthd.bak.2016-07-0121:14:19

[root@node5 config]# sed -i 's#MECH=pam#MECH=shadow#g' /etc/sysconfig/saslauthd

[root@node5 config]# grep -i mech /etc/sysconfig/saslauthd

# Mechanism to use when checking passwords.  Run "saslauthd -v" to get a list

# of which mechanism your installation was compiled with the ablity to use.

MECH=shadow

# Options sent to the saslauthd. If the MECH is other than "pam" uncomment the next line.





3、配置ldap方式验证用户

# /etc/init.d/saslauthd restart

Stopping saslauthd:                                        [FAILED]

Starting saslauthd:                                        [  OK  ]

[root@node5 config]# testsaslauthd -ulily -plily

0: NO "authentication failed"

[root@node5 config]# grep lily /etc/passwd

[root@node5 config]# id lily

id: lily: No such user

[root@node5 config]# useradd lily

[root@node5 config]# passwd lily

Changing password for user lily.

New password: 

BAD PASSWORD: it is too short

BAD PASSWORD: is too simple

Retype new password: 

passwd: all authentication tokens updated successfully.

[root@node5 config]# testsaslauthd -ulily -plily

0: OK "Success."

# testsaslauthd -utom -ptom

0: NO "authentication failed"





修改验证模式为ldap

# sed -i 's#MECH=shadow#MECH=ldap#g' /etc/sysconfig/saslauthd

[root@node5 config]# grep -i mech /etc/sysconfig/saslauthd

# Mechanism to use when checking passwords.  Run "saslauthd -v" to get a list

# of which mechanism your installation was compiled with the ablity to use.

MECH=ldap

# Options sent to the saslauthd. If the MECH is other than "pam" uncomment the next line.





编辑saslauthd.conf文件，默认不存在，需要自己添加

vim /etc/saslauthd.conf 加入如下内容：

ldap_servers: ldap://chinasoft.com/

ldap_bind_dn: cn=admin,dc=chinasoft,dc=com

ldap_bind_pw: chinasoft

ldap_search_base: ou=People,dc=chinasoft,dc=com

ldap_filter: uid=%U

ldap_password_attr: userPassword





# /etc/init.d/saslauthd restart

Stopping saslauthd:                                        [  OK  ]

Starting saslauthd:                                        [  OK  ]





# testsaslauthd -ulily -plily

0: OK "Success."

[root@node5 config]# testsaslauthd -utom -ptom

0: OK "Success."





4、配置svn通过ldap验证

在ldap服务器中添加svn.conf文件，默认没有该文件，需要自己添加

# vim /etc/sasl2/svn.conf

pwcheck_method: saslauthd

mech_list: PLAIN LOGIN





svn服务器中修改svn服务器配置

# cd /application/svndata/sadoc/conf/

# sed -i 's@# use-sasl = true@use-sasl = true@g' svnserve.conf

# grep use-sasl svnserve.conf

use-sasl = true

[root@node2 conf]# /etc/init.d/svnserve stop

[root@node2 conf]# pkill svnserve

[root@node2 conf]# lsof -i :3690

启动服务

[root@node2 conf]# svnserve -d -r /application/svndata/

[root@node2 conf]# lsof -i :3690

COMMAND    PID USER   FD   TYPE DEVICE SIZE/OFF NODE NAME

svnserve 35415 root    3u  IPv4 557724      0t0  TCP *:svn (LISTEN)





修改svn服务器apache配置

# vim /etc/httpd/confhttpd.conf





<Location /svn>

    # SVN配置

    DAV svn

    SVNPath /application/svndata/sadoc/

    SVNListParentPath on

    AuthType Basic

    AuthName "svn for project"

    AuthUserFile /application/svnpasswd/webpasswd

    AuthzSVNAccessFile /application/svnpasswd/authz

    Satisfy all

    Require valid-user





    # 在ldap找不到账号的情况下可以使用其它的认证方式(如,密码文件)

    AuthzLDAPAuthoritative off

    # openLDAP的管理账户

    AuthLDAPBindDN "cn=admin,dc=chinasoft,dc=com"

    AuthLDAPBindPassword chinasoft





    AuthBasicProvider ldap

    # 认证数据来源："ou=People,dc=chinasoft,dc=com" 下所有子entity的uid作为认证用户名

    AuthLDAPURL "ldap://192.168.8.43:389/ou=People,dc=chinasoft,dc=com?uid?sub?(objectClass=*)"





    # 设置目录权限，实现列表所有工程目录

    Options Indexes FollowSymLinks

    Order allow,deny

    Allow from all

</Location>





查看错误日志定位问题：

# tail /var/log/httpd/error_log

[Tue Jul 05 14:40:18 2016] [error] [client 192.168.50.122] user lily: authentication failure for "/svn/": Password Mismatch

svn通过ldap验证小结：

1.配置成功saslauthd

2.在ldap服务器中配置/etc/sasl2/svn.conf

3.配置好svn服务，并且开启sasl支持，重启svn

4.配置authz授权ldap用户访问项目

5.配置httpd.conf授权通过ldap访问





注意：

通过ldap认证的用户，必须在svn和ldap中添加相同账号，并且密码必须一致，否则无法访问
