hi
my apologies for this lateness of this summary. my ordinal posting described a
problem where i could not always see secondary groups for an account. that
posting is included at the end of this message.
i have not had the time to test the suggestions made. part of the problem
which i did not include in my original posting is that another group manages
the NIS domain here. so some of the suggestions i can not implement, for
example insuring that when updating the NIS maps that all maps are updated,
not specific ones. and since MIS moved the DNS/NIS server last weekend, who
knows if the problem will continue or be replaced with another weird one.
thomas anders did report that he had experienced the same problem and just
waiting seemed to clear up the problem. that has been my observation as well.
the suggestions to test included:
1. check if the netid map is updated and pushed.
2. execute make rather than update a specific map as weird things happen if
all maps don't get updated and pushed.
3. check for the NIS tolken, +:, at the end of the /etc/group file.
i had already done this.
4. check for blank lines in the /etc/group file.
this was not a factor as the problem was observed on a machines with a fresh
install from the Sun OS CD-rom and the /etc/group file was not modified
except to add the NIS tolken.
5. check that the maps on the slave server are complete.
i had already done this.
thanks to everyone who responded.

original messages:
i have a situation where i can't always see a secondary
group for a particular user. this happens using any
of the commands: groups id or newgrp. we are using NIS.
the NIS maps have the correct information. the workstations
run Sun OS 4.1.3 and 4.1.4 and Solaris 2.5.1. the NIS
master runs Sun OS 4.1.3. Most of the NIS slave servers
run Sun OS. I configured 1 Solaris machine as a slave
server with NSKit so that I know that it is configured
correctly.
sometimes the problem happens on a client, and the NIS server
shows the correct information, sometimes not. when i wrote
this summary, only the Solaris machines are giving the
correct information.
here are examples of the problem:
the user account lance has the following groups identified:
primary: des_auto
secondary: micropro, telecom
on the NIS client train_f4:
train_f4# uname -a
SunOS train_f4 4.1.4 5 sun4m
train_f4# ypwhich
sunplot3.dalsemi.com
train_f4# id
uid=12371(lance) gid=4301(des_auto) groups=4301(des_auto),4300(micropro)
train_f4# groups
des_auto micropro
train_f4# ypcat -k group | grep lance
micropro micropro:*:4300:mholland,brucet,brox,iida,lance
telecom telecom:*:4200:lance,cmartin
on the NIS slave server sunplot3:
sunplot3# uname -a
SunOS sunplot3 4.1.4 2 sun4m
sunplot3# ypwhich
sunplot3
sunplot3# groups lance
lance : micropro des_auto
on the Solaris NIS slave server ecad4:
ecad4# uname -a
SunOS ecad4 5.5.1 Generic_103640-18 sun4u sparc SUNW,Ultra-4
ecad4# ypwhich
beta
ecad4# groups lance
des_auto micropro telecom
ecad4# ypcat -k group | grep lance
micropro micropro:*:4300:sandelin,jtwomey,mholland,brucet,brox,iida,lance
telecom telecom:*:4200:cton,dmurphy,iida,snyder,lance,cmartin
on the NIS slave server sunplot1, which is bound to ecad4:
sunplot1# uname -a
SunOS sunplot1 4.1.3 2 sun4
sunplot1# ypwhich
ecad4.dalsemi.com
sunplot1# groups lance
lance : micropro des_auto
sunplot1# ypcat -k group | grep lance
micropro micropro:*:4300:sandelin,jtwomey,mholland,brucet,brox,iida,lance
telecom telecom:*:4200:cton,dmurphy,iida,snyder,lance,cmartin
has anyone run into this sort of thing before? i don't know if this
is a patch problem, an NIS problem, or what.
thanks very much.
