Stress testing sssd - group enumeration
by Ondrej Valousek 29 May '12

29 May '12

Hi all, I have been testing sssd - i.e. enumerating groups as per RFC2307bis (AD schema) in our (fairly large) organization and here are the results: sssd 1.5.1 - 5:08 minutes sssd 1.8.3 - 1:24 minutes Centrify (commercial product) - 34 seconds The performance gain between sssd 1.5.1 and 1.8.3 is obvious, but it is still far behind a commercial product Centrify. Note that when computing the groups membership, Centrify also considers the AD-specific 'PrimaryGroupID' attribute - this is something sssd can not do yet.

hello and corrupted db
by Angel Bosch 24 May '12

24 May '12

first of all: HI! nice to see a users list for this project :) and now the real dirt: I'm having problems of corruption with one of several fresh installed machines. seems that cache_*.db is corrupted periodically. after some time of working, user cant work and console says that he doesn't exist. if I execute `id' I can see extrange big numbers instead of real GIDs. the only thing that seems to work is stopping service, removing cache, and starting service again: service sssd stop rm /var/lib/sss/db/cache* service sssd start this is only happening on one machine of about 10, but all are fresh installations of ubuntu 12.04 with official packages. anyone detected similar problem? abosch
