[SunHELP] Maximum users on a Solaris 2.6 server

[Steven B. Parsons]

root at twister[607]> more /usr/include/sys/param.h | grep MAXUID
#define MAXUID          2147483647      /* max user id */

Im guessing that if I uncomment that out and do a reconfig reboot
I should be good . Currently there is nothing set for that variable and
im not able to find out what the default is.
