  • 1.  LDAPS in QRadar

    Posted Thu November 18, 2021 06:31 AM
    Hello Experts,

    I am trying to configure LDAPS on QRadar, it is showing the below error when i click on test connection. I have pulled the ssl cert from my ldap server following the link https://www.ibm.com/support/pages/node/6413273. I can confirm that the certificate is in the /opt/qradar/conf/trusted_certificates,




    Also, ran update-ca-trust.

    Kindly assist.

    Hello @benlinux ,

    I guess you have to restart your tomcat instance to take that in effect (test it on a lab before !!)

    For my point of view :

    you have to plug the certificate of the LDAPs server on :

    /opt/qradar/conf/trusted_certificates/


    Example with a Redhat IDM (Free IPA) serving as LDAPs server.

    openssl s_client -connect yourLDAPServer:636 -showcerts </dev/null 2>/dev/null | openssl x509 -outform pem > idm_ldap_server.pem

    openssl x509 -in idm_ldap_server.pem -text -noout

     

    I don't know if you are using your own PKI, but if so you have i guess to plug your CA in :

    cd /etc/pki/ca-trust/source/anchors

    For example : YOUR-CA.cert.pem

    Then do an update-ca trust.

     
    On the LDAP interface (for my example with Redhat Identity Manager / Free IPA) :
    Repo Id : Free IPA IDM
    Server URL : ldaps://idm.zoldax.demo:636
    Encryption : LDAPS
    Search Entire Base : True
    LDAP user Field : uid
    User base DN : cn=users, cn=accounts, dc=zoldax, dc=local
    Referral : Follow

    Then as Login DN (one with credentials) : uid=qradar, cn=users, cn=accounts, dc=zoldax, dc=local

    For the groups i'm using my LDAP group entry.

    Hope this helps,
    Regards,
    Zoldax

    Hi,

    I can absolutely confirm the procedure as described by zoldax. The important step is indeed to restart the tomcat service. Then the LDAPS test connection works successfully.

    Issue has been resolved, the issue was the certificate.

    I was given new certs, and after placing these certs in the /opt/qradar/conf/trusted_certificates it worked, i did not do anything other than replacing the certs.

    Thank you Pascal and Ralph.
