Hi,
This email is regarding my earlier post to the list regarding broken NIS clients.
There seems to be a bug in libc6 I got following two responses from debian users list.
Response 1: http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=206294 http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=204711
Probably you should downgrade libc6 for the moment.
Response 2: Basically, you need to change the nsswitch.conf file from 'compat' to 'nis files' for the relevant lines, afairc.
I downgraded libc6 on my m/c to the libc6 from testing section and it worked fine.
I also tried this second alternative but that broke my local users.
Hope this helps someone.
