Hi,

I'm Software Engineer from UAB in Catalonia. I devoloped a Survey Tool for my university ten years ago, and now we are thinking to change our Sorvey Tool to LimeSurvey.
Now I'm testing LimeSurvey and have many questions.

First of all, I install the last version of LS. We use a single sing-on CAS for the authentication of all user of university, and i installed the CAS LOGIN Plugin.

Then i modifed the MySql tables, and disabled autoincrement and use the univeristy id for de User ID.

Well, now I need join the participant ID with the same University ID when the people Log-in Via CAS, and not use the token or mail validation.

I try change the table of participants like user table, disable AutoIncrement and change the ID for the University ID from a Excel or csv charge.
And when anyone new login, apears in User Table, but i can't see the the Survey in the Survey List.

Thanks for your time and help

I think best os to create a plugin to «authenticate» public user

This manual.limesurvey.org/BeforeRegister or manual.limesurvey.org/BeforeSurveyPage can be used.

And « I need join the participant ID with the same University ID when the people Log-in Via CAS» really bad solution … save it elsewhere or in an attribute, but don't broke auto increment
