Mail keeps asking for password and icloud setting do not load in system preferences
Hi,
I have a mac mini server with mavericks, i have 2 iMacs as clients running mavericks too, when i use iMac (A) mail app and icloud work fine, them i take iMac (B) and mail app start asking for password , it just won't take the password, icloud do not load and cannot use anything else on system prferences because it locks system preferences, i need to force quit system prefrences , so I return to iMac (A) and i get same behaivor as iMac (B), i would appreciate your help for finding a solution for this.
All network users get the same behaivor, local users do not get this behaivor.
Thanks
Hector
