Ran a test earlier. SME 8.0 server, no contribs, using package e-smith-samba-2.2.0-53.el5.sme, not e-smith-samba-2.2.0-54.el5.sme from sme-testing. Applied old .reg (from server) to Win7pro workstation, joined it to samba domain. After merging the updated .reg (created manual) to client registry, login time dropped by 25sec. Only difference was the last line of the .reg file. So, running the test package is apparently unnecessary. Did I miss something?
