APAR status
Closed as program error.
Error description
When using a secure LDAP server that uses intermediate certificates or uses a custom enterprise Root CA, authentication will fail. A service trace will show "Failed when validating user: USER. Error: Error: unable to get local issuer certificate" The caPath property from the server.conf.yaml or node.conf.yaml file is ignored for LDAPS connections leading to certificate validation errors.
Local fix
Setting the environment variable NODE_TLS_REJECT_UNAUTHORIZED=0 will disable all TLS certificate validation in the Admin REST API and Web UI and as such should not be used in a production system but can be set as a temporary workaround on development systems.
Problem summary
**************************************************************** USERS AFFECTED: All users of IBM App Connect Enterprise v11 who use LDAP authentication and connect to a secure LDAP server using LDAPS where the remote server's certificate is signed by a certificate chain that is absent from the host system certificate store for the Integration Node or Integration Server. Platforms affected: MultiPlatform **************************************************************** PROBLEM DESCRIPTION: When using a secure LDAP server that uses intermediate certificates or uses a custom enterprise Root CA, authentication will fail. A service trace will show "Failed when validating user: USER. Error: Error: unable to get local issuer certificate" The caPath property from the server.conf.yaml or node.conf.yaml file is ignored for LDAPS connections leading to certificate validation errors.	
Problem conclusion
The configuration YAML property "caPath" is now correctly searched by the LDAP authentication system to pick up additional certificates to validate the remote server. The caPath property must be a full path to a directory on the system which contains plaintext certificate files that complete the chain of trust for the LDAPS server's certificate. --------------------------------------------------------------- The fix is targeted for delivery in the following PTFs: Version Maintenance Level v11.0 11.0.0.6 The latest available maintenance can be obtained from: http://www-01.ibm.com/support/docview.wss?rs=849&uid=swg27006041 If the maintenance level is not yet available,information on its planned availability can be found on: http://www-1.ibm.com/support/docview.wss?rs=849&uid=swg27006308 ---------------------------------------------------------------
