User ID and password constraints in Enterprise Server

Enterprise Server emulates the mainframe operating system on Microsoft Windows, UNIX and Linux operating system platforms. Mainframe user authentication constraints and technical limitations are therefore emulated through the Enterprise Server External Security Facility (ESF) Manager to ensure mainframe compatibility.

These constraints and technical limitations apply to many components of Enterprise Server including:

CICS
Job Entry Subsystem (JES)
Micro Focus Directory Server (MFDS)
IMS

User IDs and passwords are limited to a maximum of eight ASCII characters.

To avoid issues with user signon and similar functions, avoid attempting to create user IDs or passwords that do not meet these requirements.
