Symptoms

On : 11.1.1.9.0 version

1. OID 11g sync with Active Directory

2. OID Java External Authentication plugin setup in OID as documented on:

How to Configure or Setup Java External Authentication Plugins in OID 11g (Doc ID 1270329.1)

3. Enable TLS 1.2 in the Active Directory server.

4. Review suggestions from next doc id but not help:

OID Java Based External Authentication Plugin to AD Bind/Compare Fails with: ldap_bind: Invalid credentials (Doc ID 2067771.1)

5. Testing ldapbind to AD server directly works fine. 

ERROR
-----------------------
FYI. Successful ldapbind  connecting directly to the LDAP VIP but using the OID server it fails.

$ ldapbind -h <ACTIVE_DIRECTORY_SERVERNAME> -p <AD_SSL_port> -U 2 -D "<USERID_AD_SERVER>@<AC_DOMAIN> -w -W file://tmp/adwallet -P
bind successful

6. Testing ldapbind using OID serve fails with "Invalid credentials" message

$ ldapbind -h <OID_SERVERNAME> -p <OID_NON_SSL_PORT> -D "<OID_USER_DN>" -w <AD_USER_PASSWORD>
ldap_bind: Invalid credentials

STEPS
-----------------------
Enable TLS 1.2 in the third party ldap server. On this case Active Directory server.
