It's resolved. There's been many changes from Fedora 7 to RHEL 6/CentOS 6.3. One was a system authentication app. Dovecot was configured correctly, but the app was set to kerebos (sp?). Once I made the app match plaintext all worked. I set up the Fedora web/mail server some years ago. It's been running smoothly ever since except that user growth plus expanding the website created a growing performance hit---hence the new, faster, larger box. My learning curve is still steep discovering and understanding the changes since Fedora 7. mw -- "Lose not thy airspeed, lest the ground rises up and smites thee." -- William Kershner http://crucis-court.com http://www.crucis.net/1632search On 10/08/2012 04:51 AM, John Doe wrote: > From: Mike Watson<mikew@xxxxxxxxxx> > >> However, another user on the same system works! >> User bob was the one I created on the initial CentOS install, joe was >> added later. > So, did you compare bob and joe...? > Looks the same in passwd, group, shadow? > Checked requirements in pam.d? > Used ID> 500 ? > > JD > _______________________________________________ > CentOS mailing list > CentOS@xxxxxxxxxx > http://lists.centos.org/mailman/listinfo/centos > _______________________________________________ CentOS mailing list CentOS@xxxxxxxxxx http://lists.centos.org/mailman/listinfo/centos
