Modification of customer login mechanism

[vaverka]

Hello,

I'd like to ask if someone solved this situation

I have webpages in php where all of our customers going over auth section for resources and have access to old ticket system.
Now we are deploying OTRS, i have allready connected customer db backend and also can auth over standard customer.pl page with same credentials like in old system (developed customer auth module)
In this model customer has to login twice. So I would like to pass information about user to otrs or skip customer.pl.
I have otrs on same domain and server where is old system. I have information in coockies that customer is authtenticated.
All SSO variant included ldap/AD which i don't have.

Can you give me some idea what should i need modify / rewrite or when to search. Is this possible to make this type of modification?

Best regard

Here is my final solution update.

I modified my CustomAuth module to check for speciffic cookies and values to make authentication.
In my old system I used link from https://<otrs_ip/otrs/customer.pl?Action=Login

Which force to auth mechanism.
