Hello, Lars, what type of of authentication are you using? I don't know if this is related but in the past I have had trouble with the MSXML COM/C++ stack and Digest authentication with Calendar Server. But Basic authentication worked. I didn't try Kerberos. Since then I've switched to the System.XML .Net stack and haven't had a chance to test digest and kerberos authentication. But at least Basic still works. I've seen similar issues with other servers too. I had to switch from HTTP 1.1 to HTTP 1.0 because there was an issue with the .Net HTTP stack and Tomcat ( think it dealt with HTTP Continuations ) Regardless, which stack is at fault ( probably MS :-) ), It may help a lot of client developers if the Calendar Server HTTP stack was tested and found compatible with the MS COM ( MSXML ) and .Net ( System.XML ) HTTP stacks. I would imagine that a lot of CalDAV clients will be based on these. Best regards, Kervin ----- Original Message ----

Yes my browser is prompting for a login and password

With Mozilla everything works fine But iExplorer results in being rejected.

Is the browser prompting you for authentication? Looks like you are

trying

to authenticate but the password is being rejected.
