Groups must be added to the local provider in order to be associated with a local user. When creating a group, you specify a group name and a GID. A SID is generated for the group.
When providers are queried for groups, groups that are duplicated on multiple providers are merged by group name. If the different instances of the same group name have conflicting GIDs or SIDs, the attributes of the local group override those of all other providers.
On the Groups tab (User Management > Groups), click Create Group.
In the Add Group dialog, enter the group's Name and GID.
The group is created.
To manage local groups via the CLI, use the following commands.
