I have updated Horde groupware webmail edition from 5.1.x to 5.2.x. Now none of the users can access their Horde mail now. Seems all the password has reset. Kindly help me on this issue.
These forums are Directadmin related forums. Directadmin does not support Horde. You'd better ask for a help on the Horde community forums or mailing lists.
