check the "usermod" command, with "-g" option to add a primary group, and "-G" to add secondary group:
#usermod -g group username

or maybe you can edit the /etc/passwd if you know how to.

What is the difference between a primary and secondary group for an user?

Primary Versus Secondary Groups
One final note on groups is that it is important to understand the difference between the primary and secondary group. A user can only be a member of one primary group. The primary group is the group that any files they create will belong to by default. However, a user can be a member of multiple secondary groups.

The primary group is the one that is listed in the /etc/passwd file along with the user's entry. Any other group that the user is a member of in /etc/group is considered to be a secondary group.

be a member of a secondary group means that this user will have same privileges that users in this group?
