I tell him that today I had problems with some users when registering at the fortigate as 100 users approximately 4 are having problems paying your username and password,
 they enter windows with your network password later to enter Internet must register to fortinet through the web page and then is output to the Internet, 
I have 3 levels of users level 1 is free outlet to the Internet, Level 2 restricted and entitled to download pages, Level 3 where the most users and are restricted and
unable to download pages, and only with some Level 2 have trouble putting your username and password appears to them that they can not connect to the internet and
the log fortinet not appear to me that they have been registered and the problem was solved when I record with a score of Level 1 ,,,
 what makes me weird is that not all Level 2 have the problem are just some ,,,, anyone who has any idea where he might be the incident since I've searched but nothing comes out

joseraymundo,

a few questions to help narrow down the problem.

how do you put people in the level 1,2,3? do you use tcp/ip addresses? groups in Active Directory? local accounts?

How do you authenticate the users? Is it local, RADIUS or Single Sign On (FSSO)?

How do you block the level 1,2,3 - proxy or do you have a separate rule for each group?

Hi Mbutler522010

I assign multiple profiles on the fortinet , depending on the profile will be assigned the type of restriction on the Internet , 
users sign in with their AD user network when the user enters their username and password appears on page error connecting the website, 
this only happens with 2 or 3 users per day, to fix have to give an IP release, i have a separate rule for each group.
