PH72188: IBM Z OPEN EDITOR DOES NOT PROMPT FOR USER/PASSWORD DURING ADVANCED CAPABILITIES LICENSE RETRIEVAL, RESULTING IN HTTP 401

APAR status

• Closed as fixed if next.

Error description

• When IBM Z Open Editor 6.5.1 fails to use Zowe secure
  credentials, then the user doesn't get prompted for their z/OS
  user ID and password when attempting to retrieve or renew the
  license required for Advanced Capabilities.
  Consequently, the authentication request is sent without valid
  credentials and is rejected with HTTP status 401.

  2026-06-03T08:35:18.335-05:00 ERROR: CRRZG5149E Profile "rse"
  failed to connect to "my.zos.com" to determine and renew your
  advanced capabilities activation. Please review your Zowe
  profile's configuration and try again or contact your RSE API
  system administrator. The error returned was "Rest API failure
  with HTTP(S) status 401
  
  Manual connections through Zowe Explorer are successful because
  the user is prompted to enter their user ID and password when
  required.
  
  Steps followed:
  - Create a Zowe RSE profile and enter your z/OS user and
  password
  - Credentials fails to be stored in the Windows Credential
  manager
  - Automatic activation of Z Open Editor fails with an error 401
  - On Zowe Explorer, create a dataset filter
  - User enters user and password again
  - Datasets are listed
  

Local fix

• Configure the RSE profile to use non-secure credentials in
  zowe.config.json by explicitly specifying the user and password
  properties and removing them from the secure section.
  
  "your_rse": {
   "type": "rse",
   "properties": {
     "port": 6834,
     "host": "your.host.com",
     "basePath": "rseapi",
     "protocol": "https",
     "rejectUnauthorized": false,
     "codePage": "1047",
     "user": "youruserid",
     "password": "yourpassword"
   }
  }
  
  Remove the following entries:
  
  "secure": [
   "user",
   "password"
  ]
  

Problem summary

• automatic activation of advanced capabilities failed if the
  default RSE profile did not contain credentials. Users are now
  prompted for missing credentials when the
  zopeneditor.advancedCapabilities.enableRseApiActivationCheck
  setting is enabled
  

Problem conclusion
