Fix: nds_nss_getgroupsbymember: failed to init socket

I received these messages on a system I tested SuSE LUM on:

71 cron cron error suselum cron[21108]: nds_nss_getgroupsbymember: failed to init socket, status = 0 01 Mar 2010, 03:30:01
72 cron cron error suselum cron[20542]: nds_nss_getgroupsbymember: failed to init socket, status = 0 01 Mar 2010, 03:15:02
73 cron cron error suselum cron[17209]: nds_nss_getgroupsbymember: failed to init socket, status = 0 01 Mar 2010, 03:00:01
74 cron cron error suselum cron[17404]: nds_nss_getgroupsbymember: failed to init socket, status = 0 01 Mar 2010, 02:45:02

Turned out I still had the nsswitch.conf file configured for LUM while LUM was already deconfigured:

passwd: compat nam
group:  compat nam

Which had to be changed back to

passwd: compat
group:  compat
