We have about 12 iphones in our organisation and at the moment we have (again) 1 user where the phone is asking the password each morning he turns his phone on.
I've found i'm not the only one who have seen this behavior (on the forum). But no solution for it.
We are using ldap auth to eDir.

I don't know where i have to search for.
I think when i'm deleting his exchange account from the phone it's solved, but i want to know why this happends.
