I got no response when I do ldapsearch like this.
> ldapsearch -x -D "uid=joe,ou=people,dc=example,dc=org" -w joe -b "ou=group,dc=example,dc=org" "(objectclass=*)"
# extended LDIF

this is ldif file for user and group

ou: group

description: This is an example user
dn: cn=c3admin,ou=group,dc=example,dc=org
objectClass: groupOfNames
cn: c3admin
member: uid=joe,ou=people,dc=example,dc=org
It seems like binding user and base dn are not correctly setup.
Please give me a advise for solving this problem.
I am using osixia/docker-openldap:1.2.2 for the openldap. and it has auto setting for admin user at "cn=admin,dc=example,dc=org"
docker run -p 389:389 -p 689:689 --name my-openldap-container --detach osixia/openldap:1.2.2
Update
Do search with member filter then got the error.
ldapsearch -x -D "uid=joe,ou=people,dc=example,dc=org" -w joe -b "ou=group,dc=example,dc=org" "(member=uid=joe,ou=people,dc=example,dc=org)"

result: 32 No such object

Do search with base DN then got the error.
ldapsearch -x -D "uid=joe,ou=people,dc=example,dc=org" -w joe -b "dc=example,dc=org" "(objectclass=*)"

Do search with binding admin dn, then got the 5 entries.

Your search is asking to return the entries "(objectclass=*)" below the entry "ou=group,dc=example,dc=org".
I am guessing there are none.
To find the members which are within the group ou=group,dc=example,dc=org, use a filter similar to:
"(member=*)"
to find all the entries use:
Filter: "(objectclass=*)"
Base (-b): "dc=example,dc=org"
