Domain Administrator no Authentication??

Has anybody an idea, why the Active-Directory authentication works from every location in our company with every domain-user, but if I use the Domain-Administrator-Account I always forced to use the login credentials with Captive-Portal??

Hi ITsama,

Captive Portal is triggered when firewall doesnt have "user to IP mapping". Please make sure for the IP address there is "user to IP mapping", if not its expected behavior.

Hi hshah,

I know that, the problem is that i doesn't become a "user to IP mapping". For example, if i logon on a domaincontroller with the domain administrator, i will get the captive portal. If i logon with a user which is a member of the domain administators group, i become a "user to IP mapping". And what i find really strange is that on some servers/clients it isn't a problem with the domain-admin account.

I use for "server monitoring" (domaincontroller, eventtracking) the domain-admin-account, should I use a special account for that?

Hi ITsam,

I am still unclear, does firewall learn IP mapping for domain-user ?

When you logon with the administrator credentials, you may be being ignored by the UserID agent (check your configs, as admin users are often part of the ignore list). So, when you log on with administrator credentials, the firewall may not have a mapping for you, (as administrator) and so the CP page is exhibited.

The reason folks put the administrator account in the Ignore List is to not create a mapping for that account as many services log in with that account (in the background) and can potentially overwrite the actual user to IP mapping for a user who may be at that IP address.

If that is the case, that your administrator user is in the ignore list, the CP page is to be expected but only for web browsing and https://

To not see this page, consider creating a CP policy such that it excludes your DCs so that your policy will read "no captive portal" for the set of IP addresses that are Domain Controllers - where you log on with your administrator account.

Hi sjamaluddin,

I didn't use the ID-agent, I use the internal agent on the paloalto, so I don't know where to look for the ignore-list, if it's possible, but now I understand the problem. Really good explanation :smileyhappy:.

Here are the ignore list instructions for Agentless User-id on the firewall.
