Scientific linux 6.4 SSHD UseLPK Arquivo de configuração inválido

Question

Eu tento setup openldap e openssh que duram as chaves da base openldap. Eu instalei o openldap-server-5.3p1 e o configurei. Também eu instale o openss-ldap-5.3p1. Adicionado esquema openssh-lpk para cn = config base. Quando tento adicionar opções do Lpk ao sshd_config, ele jura:

Starting sshd: /etc/ssh/sshd_config: line 132: Bad configuration option: UseLPK
/etc/ssh/sshd_config: line 133: Bad configuration option: LpkLdapConf
/etc/ssh/sshd_config: line 134: Bad configuration option: LpkServers
/etc/ssh/sshd_config: line 135: Bad configuration option: LpkUserDN
/etc/ssh/sshd_config: line 136: Bad configuration option: LpkGroupDN
/etc/ssh/sshd_config: line 137: Bad configuration option: LpkBindDN
/etc/ssh/sshd_config: line 138: Bad configuration option: LpkBindPw
/etc/ssh/sshd_config: line 139: Bad configuration option: LpkServerGroup
/etc/ssh/sshd_config: line 140: Bad configuration option: LpkForceTLS
/etc/ssh/sshd_config: line 141: Bad configuration option: LpkSearchTimelimit
/etc/ssh/sshd_config: line 142: Bad configuration option: LpkBindTimelimit
/etc/ssh/sshd_config: line 143: Bad configuration option: LpkPubKeyAttr
/etc/ssh/sshd_config: terminating, 12 bad configuration options

Preciso colocar correções no servidor openssh, para que ele possa pegar as chaves do openLDAP?
