MS Access, SharePoint and Security

Let's say I sign up for Office 365.
I use the SharePoint Site that comes with it to house my MS Access Lists and my compiled database *.accmde file.
Can I set up a separate sub-site with only admin access to house a list of userID's and passwords so that when the user runs the database, it looks up this list and identifies the user, type of user, and which filter for the data in the full access sites.
If that works, then I would also want to put the data in a limited sub-site and have the accmde file retrieve that data behind the scenes. I would like to limit accidental access to the data if at all possible.
Any suggestions on how to design the tool for this?

Hi FrankHayAlexcander
It seems you have the following questions about hosting Access data on Office 365
Can Access connect to multiple SharePoint sub-site?
Can you store User info in one sub-site to control what data the user sees?
Can you hide these sub-sites so that users can't accidentally see this data?
The short answer is that I'm not sure that what you are trying to do is even possible in a Web database published to SharePoint, and certainly would be very difficult in a traditional database.
If you create a Web database in Access 2010 and publish it to SharePoint, then it is limited to the tables / SharePoint Lists in that sub-site.
In this case the credentials of the user are passed to SharePoint to retrieve data. This means that to read the list the user would have to have permissions and so they could go out the site directly and see the same data.
Using SharePoint permissions you could control what the user can see, but Access isn't going to be able to add much to that.
If you create a traditional database, then you can link to lists in multiple SharePoint site as well as other providers like SQL, and Excel.
When you created the link table here you have the option to store the credentials with the linked table.
If you do not store the credentials the user will be prompted for the credentials to use.
You could store the credentials for an Admin user when you link the table, but the problem is that if a user opens your database in the full version of Access can get to the linked tables, they will be able to see all of the data anyway.
When it comes to security, the best answer is always to secure the data using the native features of the data store such as SharePoint, SQL, etc.

Hello Stephen,
Exactly how long is "an extended period of time?" Also, is this period enforced in the controller in some way, and if so, can it be configured?
I'm asking because I have a WLAN for guests with a pre-authentication ACL allowing VPN traffic (ESP, IKE, SSL).
For "normal" use of this guest WLAN you have to click on an "accept" button on a captive portal page before you can get anywhere with traffic not matching the pre-auth ACL.
The pre-auth ACL does actually work, but it stops passing any traffic after 5 minutes of use per user. This happens every time and is 100% repeatable.
So I'm very interested to know if we can change this apparent 5 minute restriction in some way.
Thanks!

Access 2013 and SharePoint Foundation/Server 2010

I have a real simple scenario that keeps happening.
I simple click external data -> More -> SharePoint List from Access 2013 and point it to a SharePonint 2010 list ... then link the list. It will link and show the data. Once... After closing the access file, it just freezes when opening
it again.
I've tried this on several windows clients (win7 and 8) and 2 different SharePoint 2010 installs (1 being Foundation, the other being Server). Both are service packed.
Any ideas?

I believe i too am running into this issue.
I have a CRM application i created in Access 2010 which links to lists on Sharepoint Foundation 2010 (As bundled with Small Business Server 2010) using SSL. I have this application running on various client machines, some on the local network and some via
the internet. Until now we have been entirely Access 2010 and whenever a new client was required i just copied over the Access front end and it just worked.
We have a new PC which has Win7 Pro 64bit and Office 2013 Pro. I copied over the front end but when i try and open one of the linked sharepoint lists Access just hangs with the spining circle. I have no problem accessing these lists on SP via Internet Explorer
and furthermore if i select "Open with Access" and link a list it then opens within Access 2013 OK, (although Windows Security does prompt for the users password). However, if i save this database and re-open it i can no longer open the list!!
I have noticed that if i run Access 2013 as administrator and open the front end application then there is no problem.
Possible permissions issue???
If i repeat what Eric describes, Access 2013 shows me all the lists on out SP site and successfully links it (i.e. It appears under Tables) however, unlike Eric the list won't open (not even once).

Sharepoint and SSRS integration Error Requested registry access is not allowed.

I have integrated SSRS with sharepoint foundation 2010, it was running fine but suddenly its starts giving me error as -
"An unexpected error occurred while connecting to the report server. Verify that the Reporting Services Service Application mapped to this web application is available OR the report server is available
and configured for SharePoint Integrated mode. --> The report server cannot decrypt the symmetric key that is used to access sensitive or encrypted data in a report server database. You must either restore a backup key or delete all encrypted content. --->
Microsoft.ReportingServices.Library.ReportServerDisabledException: The report server cannot decrypt the symmetric key that is used to access sensitive or encrypted data in a report server database. You must either restore a backup key or delete all encrypted
content. ---> System.Security.SecurityException: Requested registry access is not allowed."
Now i am not able to read reports or cant access all database options in sharepoint,it says
registry access is not allowed
I tried to reset encryption key and allowed all access to registry keys buts its giving same error .
Please suggest me what should i do now, i stuck here...

Hi Bhagyashri,
From your description, there have two questions in the environment:
"Requested registry access is not allowed" while access SharePoint sites
and "The report server cannot decrypt the symmetric key that is used to access sensitive or encrypted data in a report server database" while viewing reports
For the first issue, the cause is the SharePoint web service account can't access some registry keys.
For the second issue, the cause is that the report database was restored from another server, and the encryption key was not restored correctly.
To fix the issue, please:
Follow "solutions" in this article
http://blogs.technet.com/b/spsforum/archive/2011/11/02/quick-solution-5-requested-registry-access-is-not-allowed.aspx to fix "Requested registry access is not allowed"
Restore the encryption key again, or please delete the key and then reset every credential setting in SSRS data source connection

Sharepoint and SSRS report trust relationship ssl/tls secure channel remote certificate is invalid

I have no experience with sharepoint at all. but this is what I observed.
I intermittently getting this error message on my sharepoint. could not establish trust relationship for the ssl/tls secure channel. Remote Certificate is invalid according to the validation procedure.
Screnshot of the error
This is how the sharepoint page layout.
I have report.aspx. and below is the content of the aspx file.
The url is http://sharepoint.COMPANY.com/Pages/Report.aspx.
The URL is intranet only.
The sharepoint is hosted in SERVER1 and the SSRS is hosted in SERVER.
I observed this error happens on both HTTP and HTTPS http sharepoint COMPANY com/Pages/Report.aspx OR https sharepoint COMPANY com/Pages/Report.aspx
So far, the step I did was to follow this blog http://krishnasangani.blogspot.ca/2013/06/the-remote-certificate-is-invalid.html Restarted
IIS in SERVER1 AND SERVER2. but the problem persist. Another I have done is to click the certificate in internet explorer and everything looks ok on that side to (certificate is valid)
It seems to only happen earlier during the morning, then it fixes itself around 9 Oclock. It has been on going for about 2 weeks. Please help troubleshooting this.

A few questions I have in mind is Any pointer to troubleshoot this problem AND By looking at the ASPX file, Would you be able to determine what method is my Sharepoint page calling the SSRS report , integrated mode, native mode? IEFrame? The reason I am asking
this is that maybe IF I google using the right terminology I can get to the similar problem and solution.
Thanks

Please let us know if you are using
SharePoint communicates to an external service via HTTPS
Please try perform following steps:
Fix is to setup a trust between SharePoint and the server requiring certificate validation.
In SharePoint Central Administration site, go to “Security” and then “Manage Trust”. Upload the certificates to SharePoint. The key is to get both the root and subordinate certificates on to SharePoint.
The steps to get the certificates from the remote server hosting the WCF service are as follows:
1. Browse from IE to the WCF service (e.g., https://remotehost/service.svc?wsdl)
2. Right click on the browser body and choose “Properties” and then “Certificates” and then “Certificate Path”.
This tells you the certificate chain that’s required by the other server in order to communicate with it properly. You can double-click on each level in the certificate chain to go to that particular certificate, then click on “Details” tab, “Copy to
File” to save the certificate with the default settings.
As an example, get both VeriSign & VeriSign Class 3 Extended Validation SSL CA.

Grant access to help desk users to add members to distribution and security groups

Hello,
I am trying to create a set of help desk users that has full access to add or remove members from distribution and security groups as well as update users. We want it to bypass owner approval and essentially allow this group to add or remove members
in the FIM Portal and flow it down to ADS.
This obviously works fine if one is a member of the Administrators set, but we want a second tier of power users with limitied rights compared to FIM Admins. We have added the help desk team to the Security Group Users and Group Users set as
well as MPR "Security group management: Users can read selected attributes of group resources".
The help desk users can update users in the Portal with no issue. The can search groups with no issue but when they try to add members to a group they get the error "Access Denied".
Any help is greatly appreciated.
Thanks!

I'm having very similar problem - I have users with delegated right to modify group membership only. User can add someone to group and it works fine, but when the same user is trying to remove and user from a group (even if this is the same user
which was added a minute ago) he gets Access Denied:
The
request included members which the requestor is not authorized
to add and/or remove from this group."
It is caused by default MPR:
Group management workflow: Validate requestor on remove member
Question is how this activity validates this request - any insight?

How to get Client ID and Client Secret for Office App for Word which accessing SharePoint Online

we currently implementing an Office App for MS Word which access SharePoint list and get data from lists. Our aim is any user can get this app from Office App store and enter their SharePoint URL and browse their own SharePoint lists and use those. When
I was checking mechanisms which you used to access SharePoint, in some of them have used ClientId and Client Secret to authenticate with SharePoint. I have following questions.
1.If I want to sell my app using Office app store where can I get those clientId and client secret which is used to get the access tokens.
2.Is it possible to create SharePoint app and publish it to SharePoint app store and get clientId and client secret and use it when accessing through office. So users first download our SharePoint app install it to their SharePoint environment then get out
Office App from Office app store and add it to word. Will this work?

Hi,
>> We are planning to develop an Office app to access SharePoint Online and SharePoint on Premise from Microsoft word.
I’m not very familiar with SharePoint development, so please correct me if I have any misunderstandings about your requirement.
The basic components of an app for Office are an XML manifest file and the default webpage of your app (server side).
>> If I'm publishing my Office App for Word in to the Microsoft office app store, how do I get the ClientId and ClientSecret which I need to pass to authenticate with SharePoint online?
As far as I know, when register your web app to SharePoint Online, you will get the ClientId and ClientSecret from the Azure Active Directory. And you need to store the Client ID and Client
Secret on the app server side.
For details, you could reference the article
Building an Office 365 ASP.NET MVC app.
>> If ClientId and ClientSecret not providing when we publishing Word Office App to the app store how what the ways which we can use to authenticate with SharePoint using Word Office app?
You don’t need to provide the ClientId and ClientSecret when publishing your App to App Store. They are stored on your app server side.
By the way, if you have the question about how to access the SharePoint resource in a Web Application, I will suggest you posting the questions to
SharePoint Development Forum. For this forum, we mainly discuss the questions about using the Office JavaScript API to develop Apps for Office.

Could someone please explain to me how to set-up my Apple ID so that both my password AND security questions have to be answered before access is granted? Is this possible? I am not very computer smart, so could you explain step-by-step!Very Appreciated!

The security questions will only be asked on the first purchase on a computer or device (though people have occasionally posted that they've asked for them when it isn't the first time) - I'm not aware of any way to change that. You can force the password to be required on your iPad via Settings > General > Restrictions > Require Password set to 'Immediately' (the default is a 15 minute period during which it doesn't need re-entering)

SharePoint 2013 - Site Settings - Users and permissions - "Access Request and invitations" link missing

I am site collection administrator and have configured the outgoing email in Central administration but "Access Request and invitations" link is missing, pl advice any additional configurations for this link to show up
I was though able to configure access requests by going to Site Settings->Users and permission and on the ribbon selected "Access Request Settings"
What is the difference in either of the approaches?
Thanks
Abhishek

Hi there,
I noticed this post, and didnt really find an appropriate solution to your issue. I noticed the same issue when dealing with Access Requests. First of all to make sure that the Request feature is enabled, you need to access
Site Settings -> Site Permissions -> Access Request Settings -> Make sure the
'Allow access requests' option is enabled.
The Allow access screen just allows you to enable the feature and also to specify a email address that notifications are sent to. Whereas the 'Access Requests and Invitations' section provides a screen to manage Access Requests and request history.
I noticed then that the Access Requests and Invitations link under 'User and Permissions' didnt actually appear until someone actually requests to join the site. It seems that this is needed to display the screen. Once actioned once, the option stays there.
Hope it helps

How to access Sharepoint List using a Different user. Access SharePoint List using some Authentication

Hi,
SharePoint version 2010
I am building an application in Java and would want to accesss a SharePoint List through REST. I have been trying to find out how the authentication process would work once i want to deploy it into Production.
I am not able to find anything useful to send user detail / authentication. Can you please help me out here.
Thanks,
Bhaskar.
Thanks, Bhaskar

Hi,
According to your post, my understanding is that you want to access SharePoint list from Java application through REST.
In some cases you may need to create a new access token (this is somewhat akin to "running as a different user").
Essentially, you are using a different user's security context. Typically, you would create an Active Directory account specifically for this purpose and then grant appropriate rights to the user account in SharePoint.
http://sharepoint.stackexchange.com/questions/83440/authenticate-external-systems-against-sharepoint-rest-services
There are some articles about this topic, you can have a look at them.

Accessing sharepoint REST api using S2S authentication

Hi, I'm trying to access the SharePoint REST APIs (One-Drive for business) using the access token retrieved from S2S authentication flow (https://msdn.microsoft.com/en-us/library/azure/dn645543.aspx).
Currently, I'm getting the following exception:
he server was unable to process the request due to an internal error. For more information about
the error, either turn on IncludeExceptionDetailInFaults (either from ServiceBehaviorAttribute or from the <serviceDebug> configuration behavior) on the server in order to send the exception information back to the client, or turn on tracing as per the
Microsoft .NET Framework SDK documentation and inspect the server trace log
Is this scenario (app auth instead of delegate auth) support for those set of APIs?
Thanks

Hi,
According to your description, my understanding is that you want to access SharePoint Online One-Drive for business API using OAuth 2.0 authentication.
In summary, Rest API can work with OAuth 2.0 authentication.
Here are some detailed articles about access Rest API with OAuth 2.0 authentication:
OAuth 2.0 Compliant REST API
Securing RESTful Web Services with OAuth2
About accessing One-Drive for business with Rest API, you can refer the article below:
Access OneDrive for Business using the SharePoint 2013 APIs
About the error message, I suggest you can use Fiddler to track the web request to find detailed message:

Getting HTTP 403/500 errors when accessing SharePoint 2010 pages

Hi,
I'm getting intermittent HTTP 403/500 errors when accessing SharePoint Foundation 2010 pages.
When it happens, any SharePoint pages I access I get a HTTP 403 error (example: /sites/test/default.aspx) . If I don't specify a page, I get a HTTP 500 error (example: /sites/test/). What's odd is that I have non-SharePoint .NET applications running on the
same server under the "_layouts" directory and those still work just fine.
After recycling the IIS application pool, it starts to work again, but sometime won't stay up very long.
Does anyone encounter this problem before?
TIA
Also, I'm hoping to understand what the "Microsoft.SharePoint.Library.SPRequest.GetFileAndMetaInfo" method does to help me track down this issue. If you have any info on what the above method is doing, I really appreciated.
