<div class="section"><p>Will you trust SYSTEMA to ensure that USERA is really USERA (or QSECOFR is really QSECOFR)? Or will you require a user to provide a user ID and password again?</p>
|

|
|
<p>The secure location (SECURELOC) parameter on the APPC device description on the target system specifies whether the source system is a secure (trusted) location.</p>
|
|||
|
|
<p>When both systems are running a release that supports *VFYENCPWD, SECURELOC(*VFYENCPWD) provides additional protection when applications use SECURITY(SAME). Although the requester does not enter a password on the request, the source system retrieves the user’s password and sends it with the request. For the request to be successful, the user must have the same user ID <u>and</u> password on both systems. </p>
|
|||
|
|
<p>When the target system specifies SECURELOC(*VFYENCPWD) and the source system does not support this value, the target system handles the request as SECURITY(NONE). </p>
