| This command sets the primary group a user account. The username specified on | ||
| the command is the sAMAccountName. The primarygroupname is the sAMAccountName | ||
| of the new primary group. The user must be a member of the group. | ||
| The command may be run from the root userid or another authorized userid. The | ||
| -H or --URL= option can be used to execute the command against a remote server. | ||
| Example1: | ||
| samba-tool user setprimarygroup TestUser1 newPrimaryGroup --URL=ldap://samba.samdom.example.com -Uadministrator%passw1rd | ||
| Example1 shows how to set the primary group for TestUser1 on a remote LDAP | ||
| server. The --URL parameter is used to specify the remote target server. The | ||
| -U option is used to pass the username and password of a user that exists on | ||
| the remote server and is authorized to update the server. | ||
