## Developers / Auth Plugin display name

Hello

I'm trying to create my own auth module based on the SAML code.  I got a display problem when I first create an instance on the institution screen.

When I try to add an instance, it shows the popup for config parameters which looks good.  Then when I click Submit, there is one entry added to the Authentication plugin list, but with no name.  The up arrow and cross icons are there though.  When I save this institution setting and come back again, it can show the name normally and works ok afterwards for editting.

I guess I missed something in the save_config_option function?  I have a 'authname' field in the $values array which is returned at the end. Thanks for any help in advance.

You can also live-debug using the log_debug etc functions (depending on the log targets you have set in config.php) Posts: 4 ##### Re: Auth Plugin display name 18 March 2010, 4:41 AM Hi Penny, Thanks for your reply. I think I got it - the SAML code has this issue as well. The "instancename" was never initialized in the class nor is it in the default$elements array, causing it null and hence the display issue for the first time it is created.  Could be a bug?

Could you share more on the debug options that can be set in config.php?  I didn't realize the debug function and looks like it could help a lot.

It could be a bug. You'd have to ask Piers, he wrote the SAML plugin.

About the log targets.  There are various different log_ methods depending on what level. log_debug, log_info, log_warn and log_environ.  Then there are corresponding log targets, which is what is set in config.php.  They are a bitmask of where you want the different levels to go, eg LOG_TARGET_SCREEN | LOG_TARGET_ERRORLOG.

Hope that helps :)
