ldapsearch 中的输出为空

我有以下内容ldapsearch：

root@debian:~/ldif# ldapsearch -LLLQ  -Y EXTERNAL -H ldapi:/// -b dc=nodomain   -D  cn=admin,dc=nodomain,cn=Pahlevanzadeh,ou=People,uid=mohsen,loginShell=/usr/bin/csh
dn: dc=nodomain
objectClass: top
objectClass: dcObject
objectClass: organization
o: nodomain
dc: nodomain

dn: ou=People,dc=nodomain
objectClass: organizationalUnit
ou: People
description: Organizational Unit for Sales Department

dn: uid=mohsen,ou=People,dc=nodomain
uid: mohsen
cn: Pahlevanzadeh
objectClass: account
objectClass: posixAccount
objectClass: top
objectClass: shadowAccount
shadowLastChange: 20121
loginShell: /usr/sbin/csh
uidNumber: 130
gidNumber: 137
homeDirectory: /home/mohsen
gecos: A good boy,,,

但是当我使用以下内容时ldapsearch，我没有上述结果：

root@debian:~/ldif# ldapsearch  -Y EXTERNAL -H ldapi:/// -b dc=nodomain,cn=Pahlevanzadeh   -D  cn=admin,dc=nodomain,cn=Pahlevanzadeh
SASL/EXTERNAL authentication started
SASL username: gidNumber=0+uidNumber=0,cn=peercred,cn=external,cn=auth

# search result

如何使用‘-b’创建查询以获得第一个结果？
