IT36977: WEBADMIN LDAP INTEGRATION FAILURE, WHEN USING SECURED LDAP ENDPOINT, DUE TO SERVER CERTIFICATE IDENTITY CHECK.

APAR status

• Closed as program error.

Error description

• While connecting to a ldap server over TLS, the default behavior
  is to verify if the LDAP server hostname matches its
  certificate's subject name or subject alternate name. If it
  doesn't match, then the handshake fails.
  
  
  
  Users may want an option to skip the hostname verification
  check when using ldaps endpoint in ldapUrl or  ldapAuthorizeUrl
  property.
  
  
  A new property named ldapCheckServerIdentity is introduced in
  node.conf.yaml(server.conf.yaml for stand-alone integration
  servers) that can be configured to false to disable the hostname
  verification of ldap server used for webadmin security.
  

Local fix

  PROBLEM DESCRIPTION:
  While connecting to a LDAP server over TLS, to validate a web
  user trying to login,  the default behavior is to verify if the
  LDAP server hostname matches its certificate's subject name or
  subject alternate name. If it does not match, then the handshake
  fails.
  
  Users may want an option to skip the hostname verification check
  when using ldap endpoint in ldapUrl or  ldapAuthorizeUrl
  property.
  

Problem conclusion

• A new property named ldapCheckServerIdentity is introduced in
  node.conf.yaml(server.conf.yaml for stand-alone integration
  servers) that can be configured to 'false' to disable the
  hostname verification of LDAP server used for webadmin security.
