Mainframes traditionally use uppercase passwords. If your password contains lowercase or mixed-case characters, the z/OS security package may reject it unless the XCOM configuration file is specifically set with LOWERCASE_PSWD=YES Missing Remote Password: When using ISPF panels for a TYPE=EXECUTE

Given the scarcity of concrete information, it's natural to speculate about the origins and purpose of XCOMM0257E. Some theories include:

Beyond the realm of technology and computing, XCOMM0257E seems to have relevance in various industry-specific contexts: xcomm0257e

Security profiles for specific User IDs may have "Source Restrictions" that limit where they can log in from. If maintenance or system updates tighten these rules, a previously working User ID might suddenly encounter XCOMM0257E. Recommended Solutions

If a user provides a mixed-case or lowercase password but the XCOM for z/OS configuration has LOWERCASE_PSWD=NO (the default), the security package will fail to authorize it. Mainframes traditionally use uppercase passwords

To resolve XCOMM0257E, administrators and users can take the following steps:

In some interfaces, such as XCOM ISPF panels, failing to specify a password in the "Remote System Information" section can trigger this error without a specific dataset name being mentioned. If maintenance or system updates tighten these rules,
