    Hello,

    for some reason we needed to give read and contribute permissions to users for dynamically created sites using C# code. we want the site have specialized permissions so we break parent site permissions, create groups and set their permission level for the site. 

    although a specific user has read permission to this site, he gets access denied. When I go to parent site from sharepoint menu, and give the user read permission, then he could see the subsite.

    how can i handle this programmatically?

    thank you

    Attaching the code below. It starts with WebProvisioned() method.

    private void createGroup(SPWebEventProperties properties, String groupName, String groupDescription, String permissionLevel)
        {
            SPWeb web = properties.Web;
            SPUserCollection users = web.AllUsers;
            SPUser owner = web.SiteAdministrators[0];
            SPMember member = web.SiteAdministrators[0];
            SPGroupCollection groups = web.SiteGroups;
            groups.Add(groupName, member, owner, groupDescription);
            SPGroup newSPGroup = groups[groupName];
            SPRoleDefinition role = web.RoleDefinitions[permissionLevel];
            SPRoleAssignment roleAssignment = new SPRoleAssignment(newSPGroup);
            roleAssignment.RoleDefinitionBindings.Add(role);
            web.RoleAssignments.Add(roleAssignment);
            web.Update();
        } // method

 private void AddUserToGroup(SPWebEventProperties properties, String groupName, String userName)
        {
            SPWeb web = properties.Web;
            web.Groups[groupName].AddUser(userName, null, null, null);

        }

 public override void WebProvisioned(SPWebEventProperties properties)
        {
            properties.Web.Title += String.Format("[Created By: {0}]", properties.UserDisplayName);
            properties.Web.AllowUnsafeUpdates = true;
            properties.Web.Update();

            if (properties.Web.WebTemplateId == 2)
            {

                using (SPWeb web = properties.Web)
                {
                    try
                    {
              web.RoleDefinitions.BreakInheritance(false, false);
              web.Update();

                        createGroup(properties, "grpMoMSiteReaders_" + web.Name, "Readers group", "Read");
                        createGroup(properties, "grpMoMSiteAuthors_" + web.Name, "Authors group", "Contribute");

                        AddUserToGroup(properties, "grpMoMSiteReaders_" + web.Name, "WIN-TMSIGIC3N2P\\asilter");

                    }
                    catch (Exception exp)
                    {
                        CimtasLoggingService.LogError(CimtasLoggingService.CIMTAS_ERROR, exp.Message);
                    }
                }
            }
        }

    Hi asilter,

    If we want the site to not inherit the permissions from the parent site,  we need to provide the parameter "UniquePermissions" while creating the site. Otherwise, we will drop into the Access Denied scenario you mentioned.

    Here is a PowelShell script to create a site, which provides the UniquePermissions. The WebProvisioned works in this scenario:
    New-SPWeb -name "site name" -URL "site URL" -template "template" -UniquePermissions

    Thanks,
    Jinchun Chen

     Is it possible to make the site have unique permissions with c# code. Could you revise my code?

    Hi asilter,

    The code you posted is fine. Could you please post the code you are using to create site?

    If you are using SPWebCollection.Add method to create the site, please set the parameter "useUniquePermissions" to be True.

    Thanks,
    Jinchun Chen

    I added

    // obselete
    web.HasUniquePerm = true;

    above 

    web.RoleDefinitions.BreakInheritance(false, false);

    line. It worked for the site. is obselete line going to be a problem?

    Hi asilter,

    Based on my testing, we should provide the uniquepermission while creating the site.

    Thanks,
