Ldapsearch query for own entry returns "no such object", when executed by normal LDAP user.

Issue

Per below ACL, ldap user's should be able to query his own entry, but not other users.

access to attrs=userPassword
 by anonymous auth
 by self write
 by * none
access to dn.subtree="ou=People,dc=example,dc=com"
 by self read
 by * none

However, it returns "no such object" error when executed by user itself.

ldapsearch -p 389 -h xx.xx.xx.xx -D "uid=user1,ou=people,dc=example,dc=com" -b "ou=people,dc=example,dc=com" uid=user1
