I have just added Piranha CMS to an existing ASP.NET MVC 5 site but am having a strange issue.
If I am logged into the site and then try to access site.com/manager and enter the piranha login details then the page just refreshes and nothing happens (trying with an incorrect password gives me an incorrect password message but correct login details just refreshes page)
If I try accessing site.com/manager without being logged into the site then it logs me in OK the piranha manager area.
Any ideas why this is? Ideally I'd like the user to only need to login once is this possible?
The current version of Piranha CMS doesn't integrate with other authentications. For now the only solution is to keep the user accounts separate like you noticed. This feature has however been planned for a couple of years but hasn't been implemented due to various reasons.
Pulling out the authentication mechanics imposes a lot of changes on the database schema and makes setting user priviliges for specific pages much harder.
