User login
If the user now logs on he/she only sees the categories and records for which he/she has a permission and rights.
The user logs on with his/her name and his/her password. When the user logs on the first time he/she may has to arrange a new password for the login.
If the user has no rights for the right management he/she can make no changes in permissions or rights. If a user starts a password in a folder himself/herself, he/she is registered as the owner of that record and can manage the permissions and rights for his/her record himself/herself. The same also applies to the capture of categories. The user will be set up automatically with full access for his/her own record.
If a user can see no data at all after the login, neither folders nor records you have not given the accordant folder rights to that user. In order that a subordinated folder is being displayed you have to give at least the right to read on the superior folder, otherwise the folder structure can not build up.
