How to configure openldap server and client on RHEL 8

Linux
1

Hi All,

I configured openldap server and client on RHEL 8.
I get this error below on client side and been trying to troubleshoot it but can’t find the answer.

[root@client ~]# id user1

id: ‘user1’: no such user

do you know to fixed it :slight_smile: ?

thanks

Use the grep command or id command to see if the user named ‘users1’ exists or not:

grep -w '^user1' /etc/passwd
id -u user1

No such user, means you need to add a new user using the useradd command.

sudo adduser user1
grep -w '^user1' /etc/passwd
id -u user1

user1 has already added on my ldap server. client can ping ldap. I thinh my ldap config is incorrect but can’t figure it out a couple days now.

ldap server:
[root@ldap ~]# id user1
uid=1001(user1) gid=1001(user1) groups=1001(user1)

client server:
[root@client ~]# id user1
id: ‘user1’: no such user

[root@client ~]# ping -c2 ldap.example.com

yes, ldap config is not correct on your client side.

Now it’s the cert issue. may need to start it over again…

[root@client ~]# openssl s_client -showcerts -connect ldap.example.com:636
CONNECTED(00000003)
depth=0 C = US, ST = NY, L = NYC, O = OpenTest, OU = Test, CN = ldap, emailAddress = me@gmail.com
verify error:num=18:self signed certificate
verify return:1
depth=0 C = US, ST = NY, L = NYC, O = OpenTest, OU = Test, CN = ldap, emailAddress = me@gmail.com
verify return:1
