最近搭build环境testing，安装openldap，openwebmail和PAMauthentication模块遇到当前帐户loginwebmail更改密码会出现“密码错误，更改不成功..”
openwebmail.log显示
Fri Mar 21 16:50:40 2014 - [2543] (192.168.126.1) testuser - change password error - auth_pam.pl, ret -4, pam_authtok() err 10, User not known to the underlying authentication module 当前的设置
/etc/httpd/conf.d/openwebmail.conf
auth_module auth_pam.pl
/etc/pam.d/openwebmail
#%PAM-1.0 auth sufficient /lib/security/$ISA/pam_ldap.so auth required /lib/security/$ISA/pam_unix.so account required /lib/security/$ISA/pam_unix.so account sufficient /lib/security/$ISA/pam_ldap.so password sufficient /lib/security/$ISA/pam_ldap.so password required /lib/security/$ISA/pam_unix.so
不知道设置错在哪里导致这个问题？
