We have the following problem, when transferring files from XCOM for windows server to the mainframe where the following message is displayed:
XCOMM0257E ACCESS DENIED BY SECURITY INTERFACE
The credentials of the user are correct, but even so the problem persists.
Mixed or lower case passwords were being used but parameters were not set correctly for that.
Release : 11.6
Component : CA XCOM Data Transport for Windows
Change LOWERCASE_PSWD=NO to LOWERCASE_PSWD=YES in the config member.
