How can I grant modification permission to one page only

Dear Sir and Madam,

I would like to know f you could lead me to the right action to provide the permission to one of my colleage to modify only one page.

Many thank

we need to know about your system environments

Hello,

I am using MODx Revo and my web site is on a Apache web server?

What do you need exactely?

only revo/evo.
modx has 2 systems, right?

These threads might help you somehow:

See the security tutorials at the site in my sig.

Thank robray for the tuto.
I am looking for this but I would like to aks you one think before.

I think there is two defferent users.
If I want to have a secure page where I want to publish link on my CV, for example. The I will create a resoucre called "cv". Then I create an user call "job_agency". Which king of user is "job_agency"? Is a "user" (web user)? Then I should follow you tuto

Now, If I want to have my colleague able to modify pages, I will create a manager user?
http://bobsguides.com/advanced-security-operations.html

Am I right?
A user will be used for a front end access and a manger user will be used for a back end access?

Then I did the following
(http://bobsguides.com/creating-manager-users.html)
1) I created a new user called "carine"
2) I created a new role called "rl_carine"
3) I created a new user grouo called "gp_carine"
4) As I want carine to be able to modify one ressource, I di not duplicate the Standard Administrator Police template, but I duplicated the standard resource template and I called it "EditorResourseTemplate"
5) Then I duplicated the resource polices and I called it "EditorResourse" from the Access Policies tab
6) I create a new context Access ACL entry and here I have a trouble. It state to fill the filed as the following
Context: mgr
Minimum Role: Editor
Policy: EditorAdmin
But as I have not give the same name I did
Context: mgr
Minimum Role: rl_carine
Policy: HERE I CAN NOT FIND EditorResources

Why??? because I can see it from the Access Police tab. I laso can see "Resource"

Could help me with that matter?
Many thank

Yes, I think I can.

Resource policies (based on the Resource policy/template) are only for Resource Group Access ACL entries. That’s why it doesn’t show.

I’m not completely clear on what you want. If you want to protect (hide) resources in Resource Groups, you’d normally want a Resource Group Access ACL entry and a policy like the one you have.

If you want to control what a user can do, in general, in the Manager, you want a Context Access ACL entry and a policy based on the Administrator policy/template (e.g., EditorAdmin).

Hello Thank for your answer.
The only think I would like to do it to let a user (carine in my example) to modifiy the content of one page (or some pages). it is the reason why I chose ResourceTemplate

Basically, I think you want this: http://bobsguides.com/hiding-resources-in-the-manager.html.

Put all the resources on the site *except the one you want the user to access* in the HiddenResources group.
