Hi, This morning I had an issue with winbind where it lost all its uid's, I tried restarting samba and winbind but still no joy :-( The only way to fix it was to change the following : idmap config WEBHOSTING : schema_mode = rfc2307 idmap config WEBHOSTING : backend = ad idmap config WEBHOSTING : range = 500 - 300000000 to : idmap config ALLDOMAINS : schema_mode = rfc2307 idmap config ALLDOMAINS : backend = ad idmap config ALLDOMAINS : range = 500 - 300000000 Does anyone know why this problem occurs ? Is it winbind caching ? I previously had this problem when i upgraded to 3.3.9 for 3.2.15, again the fix was to change the name of the idmap config.. Any help greatly appreciated. Thanks. Wasim
