FreeRadius无法从LDAP加载客户端的问题求助

大家好，我最近在尝试把Radius客户端存储到LDAP中并调用使用，目前客户端已经在LDAP里配置完成了，用ldapsearch查询能正常查到相关条目：

$ ldapsearch -x -H ldap://ldap.example.com -D "cn=admin,dc=example,dc=com" -w admin -b "dc=example,dc=com" '(&(objectClass=freeradiusClient)(freeradiusClientShortname=client1))'
# extended LDIF
#
# LDAPv3
# base <dc=example,dc=com> with scope subtree
# filter: (&(objectClass=freeradiusClient)(freeradiusClientShortname=client1))
# requesting: ALL
#

# 192.168.10.2, clients, radius, services, example.com
dn: freeradiusClientIdentifier=192.168.10.2,ou=clients,ou=radius,ou=services,d
 c=example,dc=com
objectClass: freeradiusClient
objectClass: radiusClient
freeradiusClientIdentifier: 192.168.10.2
freeradiusClientShortname: client1
freeradiusClientType: other
radiusClientSecret: password

# search result
search: 2
result: 0 Success

# numResponses: 2
# numEntries: 1 

FreeRadius的LDAP模块已经启用了，而且当我把客户端配置写在/etc/raddb/clients.conf里的时候，模块工作完全正常，但就是没办法从LDAP加载这些客户端。有没有朋友能帮忙分析下可能的问题点，或者给点排查方向呀？
