Seems to work for me.

Also seems to work for me - have added a comment to this and the  
previous issue on bugs.horde.org

I started looking at this but came to the conclusion that its only  
going to be possible for auth backends that hold the password in  
plaintext since most crypted passwords are one way crypted. I've been  
able to find nothing about converting between them...

I think based on my couple of weeks of having an m600i those last 3  
should complete support for the m600i.

Thanks,
