Question

os login api for php on ibm as400 iseries

Asked by: richard_crist

On an IBM AS400 iSeries from within a PHP program I need to be able to authenticate a user against the system's userlist.  That is, when a user goes to my web page, which is being served directly from the i5, I want that user to be able to log in to my web page with a username and password that will be checked against the i5 userlist.  Is there a way to call an os api from php to do this?  Thank you!

I think validation list entries are the way to go. That way no user profile is required on the system, and the passwords are encrypted.
Check out this link:
http://www-912.ibm.com/s_dir/slkbase.nsf/1ac66549a21402188625680b0002037e/ae90951069974234862566f1007835e4?OpenDocument

Check the infocenter on the use of validation lists, especially the QSYADVLE API.

If you need more direction, post back!

Barry is right that validation lists are intended for this kind of usage. Maybe they are sufficient.

Your question, though, is if you can call an API from PHP.

I'm not a PHP programmer, so I don't know if PHP can call programs or not. If it can't then its usefulness would be extremely limited.

An API to verify a profile/password combination would be the Get Profile Handle (QSYGETPH) API. This is a program object, so it can be called like any other program on the system. If PHP can call programs, then it can call QSYGETPH.

More likely, PHP would call a CL program (or RPG or COBOL or C) that would call the API program. The CL program would accept profile and password as input and return a 'success/failure' indication. If successful, the CL program should then call the Release Profile Handle (QSYRLSPH) API to free up the profile token since it apparently wouldn't actually be used for anything.

See:

http://publib.boulder.ibm.com/infocenter/iseries/v5r4/index.jsp?topic=/apis/QSYGETPH.htm

Note that you'd want to be very careful in how you transported profile/password between the client browser and the system. You don't want those going across as clear text. That's another reason to consider validation lists.

My apologies for my late reply.  I found that our iSeries system has Zendcore on it and it provides an i5_connect() routine that can be called from PHP to validate a "green screen" login.  However, I like your two suggestions, which were actually more of what I was thinking of.  I will investigate your methods and compare them to the i5_connect().  It will be important to know about other methods besides the Zendcore i5_connect() in case Zendcore is not always available.  Thank you!
