  2. Hi Pony,

    Welcome to the ASPNET newsgroup.

    Regarding on the ASP.NET web sites/applications single signon, do you means
    using the Forms Authentication, if so, there does exists configuration for
    the ASP.NET forms authentication to support cross application
    authenitcating(SSO). However, this require the different applications
    (maybe on different server) share the same configuration setting(like
    machinekey...). Also, those applications should share the same primary
    domain name. like aaa.microsft.com and bbb.microsoft.com. Otherwise, since
    the authentication cookie can not be shared, cross application forms
    authentication won't work. Here are some msdn reference about forms
    authentication across multiple appliations:

    Hope this helps.
