Fixed In Version: sssd-1.9.2-18.el6 Doc Type: Bug Fix
Doc Text:
Cause: sss_cache was run after SSSD downgrade but the cache file remained from previous SSSD version. Thus sss_cache did not know how to manipulate with the cache file. Consequence: sss_cache printed confusing error message. Fix: Invalid db version error message was improved in sss_cache tool. Result: When an invalid cache version is detected, sss_cache print a suggested solution.

Comment 2 Amith 2012-11-29 15:14:35 UTC 
Verified the BZ on SSSD version: sssd-1.9.2-27.el6

As part of testing, i modified the cache sysdb version to a non-existent value (0.99z). I hope we will never have an alphanumeric version for sysdb. Subsequent execution of sss_cache commad produced a better error message. See the cmd output below:

# sss_cache -U 
(Thu Nov 29 20:33:23:126171 2012) [sss_cache] [sysdb_domain_init_internal] (0x0010): Wrong DB version (got 0.99z expected 0.14)
Lower version of database is expected!
Removing cache files in /var/lib/sss/db should fix the issue, but note that removing cache files will also remove all of your cached credentials.
