If you are getting the above error when you configured ldap from ezeelogin gui >settings >ldap, Try the following steps

 

1. Add the following to /etc/ldap/ldap.conf on client machine (ezeelogin installed server)

 

TLS_REQCERT never

 

2. Add the following to /etc/sssd/sssd.conf

 
ldap_tls_reqcert = never

 

3.  This error occurs while ceritificate verifications fails as you are using a self signed certificate. Putting a valid CA,CERT and KEY will fix the issue.
