楼主

openvpn登录采用MYSQL 用户验证，提示用户无法验证，烦请帮忙分析一下问题所在。

openvpn log如下：

服务器采用的openvpn-2.2.1 + mysql-5.0.45-7 验证工具pam-0.99.6.2-4（因为不能验证，后来重新编译了pam_mysql-0.7RC1，可以测试验证）

openvpn配置文件：就贴主要的其他配置没问题，因为采用证书登录是OK的，

plugin /lib/security/openvpn-auth-pam.so openvpn

penvpn-auth-pam.so 是从源文件编译出来的

# ll /lib/security/openvpn-auth-pam.so
-rwxrwxrwx 1 root root 12781 2011-09-21 /lib/security/openvpn-auth-pam.so1
================================================================================
# cat /etc/pam.d/openvpn
auth sufficient pam_mysql.so user=vpn passwd=ipanel host=localhost db=vpn table=vpnuser usercolumn=name passwdcolumn=password where=active=1 sqllog=0 crypt=0 verbose=1
account required pam_mysql.so user=vpn passwd=ipanel host=localhost db=vpn table=vpnuser usercolumn=name passwdcolumn=password where=active=1 sqllog=0 crypt=0 verbose=1

用 testsaslauth 验证数据库没有问题；数据库的信息就不贴了。

# testsaslauthd -u 123 -p 123 -s openvpn
0: OK "Success."
