We are faced witha n issue on solaris, using an external MySQL DB that the admin accounts just can no longer login after some time (maybe a few days). When we installed the server we created additional accounts (admin2, admin3, etc) and they worked fine after setup. Aftera few days the logins just stop working completely, no idea why.
The only way to fix it is to change false in openfire.xml and re-install to re-create the username.
Has anyone see this or know the root cause ? Its very frustrating to not be abe to login to the admin.
