In Solaris, a user can belong to multiple groups: 1 primary group and 15 secondary groups by default. However, the number of groups a person can belong to is set by the kernel parameter called NGROUPS_MAX located in the /etc/system file. You can modify this parameter to allow for a MAX of 32 groups.
Again, this applies to Solaris. not sure how other flavors handle this.
