Starting with 13.04, NIS fails when parsing long group lines (in my case, 1262 bytes).

On login, errors such as the following are repeated numerous times:

yp_all: clnt_call: RPC: Can't decode result
do_ypcall: clnt_call: RPC: Can't decode result

The root cause can be seen with ypcat, where the first long group line causes a failure:

$ ypcat group.byname
<shorter lines printed correctly>
yp_all: clnt_call: RPC: Can't decode result
No such map group.byname. Reason: RPC failure on NIS operation

Perhaps this is due to a security fix similar to this one in RHEL, where YP record parsing was limited to YPMAXRECORD (1024):

The regression this caused was reported and fixed for Fedora 18:
