9825 OSx4.4. ----------- I am in 10 groups which is fine most of the time on the Pyramid. I know there are one or two problems here, especially when doing things as root, so root is in less than 8 groups. When I mount a Sun file-system over nfs I then get a message on logging in which says "too many groups". Strictly speaking this is true, so I'm not complaining but I'd like to know "what" IS complaining. It has been suggested that the Sun nfs daemon is checking for the number of groups. So, to summarise: I am in 10 groups. I login to Pyramid with Pyramid nfs file-systems mounted and get no complaints on logging in. I login to Pyramid with Pyramid and Sun nfs file-systems mounted and I get the message "Too many groups". Can someone explain ?

The limit on the number of groups in which one may be a member is only
8 on Suns; it's 20 on the Pyrs. This relates to the "credential"
structures that get passed around, and Sun's NFS complains when it is
handed too many such groups.
See the NGROUPS #definition in <sys/param.h>.
