Fix Recommendation

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

Check Contents

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.
