Trying to integrate CA TDM portal and datamaker with LDAP, but it's throwing an error saying "not part of AD group"

TDM Web logs shows the below error:

o.s.l.c.LdapTemplate: No results found for search, base: 'OU=Users,OU=TDBFG'; filter: '(sAMAccountName=abcdef01)'.

TDM Portal is integrated with LDAP but the LDAP integration is not working due to incorrect credentials

All supported TDM  Environments

This is an LDAP configuration issue.  Work with your LDAP admin  to configure the correct values for TDM-LDAP integration.  

Download and install JXplorer on the TDM. This will allow connection to the LDAP Server to verify if the LDAP configuration values are correct.
 

When using JXplorer, you need to specify the following:

Host: LDAP HOSTNAME
Port: LDAP port (ex: 389)
BASE DN= <Enter DN used in TDM>
PROTOCOL= <Select LDAP protocol> (ex: LDAPv3)
USER DN= Use the same specified in the TDM LDAP configuration. Remember to use the fully distinguished name when configuring the username. For example,
CN=name,OU=Role-Based,OU=North America,DC=ca,DC=com
Password: <password>
