When a new "Composite" domain user is added in TDV and was granted"Access Directory" privilege for the TIBCO Business Directory , the login may fail with the "Authentication Failed".
Here is a screenshot for reference:
Root cause:
The "composite" domains on each server (Business Directory and each TDV instance) are all completely independent of,
(1) They don't share the user namespace
(2) There is no co-ordination between servers.
Hence, a SITE name needs to be specified as the domain to help partition/address the specific users.
