What does "Password cannot be changed too soon. If the problem persists, please contact your System Administrator" mean?
I changed the user password and when I try to login I get the "you must change password" prompts but then I get that message.
I am running zimbra-core-4.5.7_GA in the trial period on a Fedora Core 7 188.8.131.52-91.fc7.
I have also added the samba and posix gallery extentions for 4.5. Would that be causing any issues? (Get or contribute Zimlets, UI themes, and languages in the Zimbra Gallery - zimbra_samba Admin Extension)
