I'm new in this domain and trying to bind with active directory using spring ldap client in java. I have already googled this and tried every given solution on internet but it didn't work for me. I'm getting following exception:
021-08-02T14:14:04,377 DEBUG [AbstractContextSource] - Got Ldap context on server [********]

Following is what I've tried:
@Bean
public LdapContextSource contextSource()
{
LOGGER.atDebug().log("using given ldap server config: {}", ldapServerConfig);
LdapContextSource contextSource = new LdapContextSource();
contextSource.setUrl(ldapServerConfig.getUrl());
contextSource.setBase(ldapServerConfig.getBaseDn());
contextSource.setUserDn(ldapServerConfig.getUsername());
contextSource.setPassword(ldapServerConfig.getPassword());
contextSource.setAnonymousReadOnly(ldapServerConfig.isReadOnlyConnection());
//TODO: To add the support of TLS v1.0/v1.2/v1.3
if (ldapServerConfig.isTlsEnabled())
{
ExternalTlsDirContextAuthenticationStrategy dirContextAuthenticationStrategy = new ExternalTlsDirContextAuthenticationStrategy();
contextSource.setAuthenticationStrategy(dirContextAuthenticationStrategy);
}
return contextSource;
}
@Bean
public LdapTemplate ldapTemplate(ContextSource pooledContextSource, ContextSource contextSource)
{
LOGGER.atInfo().log("connection pooling enabled: {}", ldapServerConfig.isConnectionPooling());
return ldapServerConfig.isConnectionPooling() ? new LdapTemplate(pooledContextSource) : new LdapTemplate(contextSource);
}
private ResponseEntity<ILdapResponse> authenticate(String username)
{
ResponseEntity<ILdapResponse> responseEntity;
ILdapResponse ldapResponse;
try
{
User user = userRepository.findUserByUsername(username);
Furthermore I've tried to connect with the test server and it's working fine and successfully connected. Following are the test server details
ldap.server.url=ldap://ldap.forumsys.com:389/
ldap.server.baseDn=dc=example,dc=com
ldap.server.username=cn=read-only-admin,dc=example,dc=com
ldap.server.password=password
Also I've tried to connect with the ldap console and got the successful PROD environment connection.I don't know what i'm missing in client due to which i'm unable to connect. Please guide me if i'm missing anything. Thanks in advance
