| Description |
|---|
| While LDAP client's authentication type is ldap_auth (server-side authentication), the client sends password to the server in clear text for authentication. SSL must be used in this case. |
| ℹ️ Check |
|---|
| Run the following command to check if "authtype" is "ldap_auth": # grep -iE "^authtype:[[:blank:]]*ldap_auth" /etc/security/ldap/ldap.cfg The above command should yield the following output: authtype:ldap_auth Run the following command to check if SSL is not used in the "/etc/security/ldap/ldap.cfg" file: # grep -iE "^useSSL:[[:blank:]]*yes" /etc/security/ldap/ldap.cfg The above command should yield the following output: useSSL:yes If the first command displays "authtype:ldap_auth" but the second command does not display "useSSL:yes", this is a finding. |
| ✔️ Fix |
|---|
| Edit the "/etc/security/ldap/ldap.cfg" file to have the following line: useSSL:yes Configure the LDAP server and LDAP client to use the SSL according to AIX LDAP documentation. Restart the client daemon: # restart-secldapclntd |
