Content

If you have applied one of the following IBM i HTTP Group PTF levels and then suddenly experience authentication issues when using validation lists with your IBM i HTTP Server instance, you will need to either download and apply the resolving PTF OR remove the PTF related to the issue.

IBM i 7.6 - SF99962 levels 1, 2, & 3
IBM i 7.5 - SF99952 levels 20, 21, & 22
IBM i 7.4 - SF99662 levels 41, 42 & 43
IBM i 7.3 - SF99722 levels 59 & 60
Example IBM HTTP Directives showing a PasswdFile Validation List configured for HTTP Authentication:
<Directory /www/apachedft/htdocs>
  order allow,deny
  Allow From all
  Require valid-user
  PasswdFile library/vldl_list
 
AuthType Basic
  AuthName Validation_List
</Directory>
Resolving PTF
Temporarily apply the PTF immediately after ending the QHTTPSVR subsystem.
IBM i 7.6 - SJ05802
IBM i 7.5 - SJ05799
IBM i 7.4 - SJ05800
IBM i 7.3 - SJ05801
WRKACTJOB SBS(QHTTPSVR)
Identify the active server instance names.
ENDTCPSVR *HTTP HTTPSVR(*ALL)
ENDSBS QHTTPSVR *IMMED
Load and apply the PTF.
STRSBS QHTTPSVR/QHTTPSVR
Start the individual server instances using STRTCPSVR *HTTP HTTPSVR(<instanceName>)
 
If you are unable to apply the resolving PTF, here is a temporary workaround until the resolving PTF can be applied.
Remove the following PTF using RMVPTF.
