Re: getgroup invalid argument in /var/adm/messages

It looks like the message is coming from:

uidswap.c line 70:

        saved_egroupslen = getgroups(NGROUPS_MAX, saved_egroups);
        if (saved_egroupslen < 0)
                fatal("getgroups: %.100s", strerror(errno));

>From the man pages on getgrroups:

...

     getgroups() will fail if:

     EINVAL         The value of gidsetsize is non-zero and  less
                    than  the  number  of supplementary group IDs
                    set for the calling process.

It means that the calling process (sshd) belongs to more groups than NGROUPS_MAX is defined for. Is that the case?
