SSL VPN请教

SSL VPN下面命令可以解释一下吗，作用是什么

ldap server ldap

 login-dn cn=administrator,cn=users,dc=thinkmo,dc=com

 search-base-dn ou=sslvpn,dc=thinkmo,dc=com

 ip 192.168.56.20

 login-password simple thinkmo@123

#

ldap attribute-map thinkmo

map ldap-attribute memberof prefix cn= delimiter , aaa-attribute user-group

#

ldap scheme shml

 authentication-server ldap

 authorization-server ldap

 attribute-map thinkmo

#

domain thinkmo

 authentication sslvpn ldap-scheme shml

 authorization sslvpn ldap-scheme shml

 accounting sslvpn none

#

pki domain sslvpn

 public-key rsa general name sslvpn

 undo crl check enable

#

ssl server-policy myssl

 pki-domain sslvpn

#

2、缺省证书为什么pki domain sslvpn和ssl server-policy myssl后认会握手失败和用户认证失败，不解
