It seems that there are some special characters that are not allowed in the password for the DB Connection. Do we have a list of the Password Complexity that for the DM Connection?
Release : 14.4
Component : Identity Manager
There is was a known problem in 14.4 where special characters would cause the PWDtool to fail which is why your a combination of your special character passwords are failing.
See reference DE505991 in doc link above.
