    ClaimsIdentity error after updating to 7.5

    Using Umbraco And Getting Started
    Umbraco 7

    Trying out Umbraco 7.5 after upgrading from 7.2.8.

    I'm able to login to the backend and do things just fine. Also no problems viewing the actual site.

    Another user gets the following error when they trying to do pretty much anything (though they can log in) and when they try to view an actual page on the site:

    Cannot create a Umbraco.Core.Security.UmbracoBackOfficeIdentity from System.Security.Claims.ClaimsIdentity since the required claim http://umbraco.org/2015/02/identity/claims/backoffice/sessionid is missing

    I'm not really sure what this means and searching Google hasn't really brought up anything.

    I do also see the following error in the log, but it possibly only shows up when a user first tries to login after application startup (I'm not totally sure):

    Umbraco.Core.Security.AuthenticationExtensions - The current identity cannot be converted to Umbraco.Core.Security.UmbracoBackOfficeIdentity

    I also have this issue. seems to have something to do with the UMB_PREVIEW cookie. If i remove this i can view the site and pages again

    Did anybody find a solution for this phenomen? I see this error message several times a day in the logs but can't reproduce the behavior in order to debug. The message appearing is

    Cannot create a Umbraco.Core.Security.UmbracoBackOfficeIdentity from System.Security.Claims.ClaimsIdentity since the required claim http://schemas.xmlsoap.org/ws/2005/05/identity/claims/nameidentifier is missing

    Cheers, Mirko

    Hi Mirko,

    Look here: http://issues.umbraco.org/issue/U4-8968

    This issue was fixed in 7.5.4, but wait with upgrade until 7.5.5 is ready. There was another ugly bug in 7.5.4 (http://issues.umbraco.org/issue/U4-9195)

    Regards Tomasz

    Thanks, Thomasz. I found that one. Seems to be the reason for the phenomen.
