Re: [otrs] Can non-admins be allowed read-only access to customer / companies details?

Well, that's a whole lot of not fun. *Are multiplexing rules different for Windows Server CALs? Does authentication make a difference?* No. Like the SQL Server examples previously detailed, CALs are required for access to Windows Server whether direct or indirect. Users who are authenticated or individually identified, whether by the Windows Server software or by multiplexing hardware or software, require a Windows Server CAL to access Windows Server. I'm thinking that the Windows Server external connector license then could address that. On Mon, Oct 15, 2012 at 5:11 PM, Bogdan Iosif wrote:

There is no Active Directory specific documentation. Only general Windows Server services licensing docs: http://www.microsoft.com/en-us/server-cloud/windows-server/buy.aspx which doesn't explain very well all the details in one place. The licensing documents from Microsoft are hundreds of pages long and I'm no expert in Microsoft licensing to point you exactly to where OTRS's scenario is documented but I'll do my best to give you the basis for my opinion.

1. Here http://www.microsoft.com/en-us/server-cloud/windows-server/buy.aspxyou can see that Windows Standard is licensed only as Processor + CAL. There is no simple per processor license that would grant you unlimited users connecting to that server's services. You need additional CALs for those using the server. 2. This http://www.microsoft.com/licensing/about-licensing/product-licensing-faq.asp... entry explains that when a user / device is individually identified by Windows Server it requires a CAL. Even when Active Directory is not used. - If a user or device accesses a server running Windows Server but is authenticating via a third-party authentication application (non-Microsoft-based authentication), does the user or device still require a Windows Server CAL? -

Yes, if the user or device is authenticated or otherwise individually identified by a server running Windows Server through any other means, it requires a Windows Server CAL. The specific Windows Server CAL requirement is defined in the Microsoft Product Use Rights as follows: "You do not need CALs for any user or device that accesses your instances of the server software only through the Internet without being authenticated or otherwise individually identified by the server software or through any other means." 3. Here http://www.microsoftvolumelicensing.com/DocumentSearch.aspx?Mode=3&DocumentT... can find a huge doc on licensing. It defines multiplexing, very vaguely as: - Hardware or software you use to pool connections, reroute information, reduce the number of devices or users that directly access or use the product, or reduce the number of operating system environments (or OSEs), devices or users the product directly manages, (sometimes referred to as “multiplexing” or “pooling”), does not reduce the number of licenses of any type that you need. 4. Here http://download.microsoft.com/download/8/7/3/8733d036-92b0-4cb8-8912-3b6ab96... a document that treats a little bit better multiplexing. It's actually pretty tied to SQL Server but right under Figure 1 you can see "This includes users who view data through web-based applications or enter information into a database through an intermediary product." and that is exactly the scenario where OTRS fits in relation to Windows Server. 5. The same document from above also mentions - What is the difference between a device licensed with a device CAL and a multiplexing device? - A device CAL allows one device, used by any user, to access instances of the server software on the licensed server. A multiplexing device pools connections from other devices, which users can license with a device CAL.

All CAL licensing is actually focused on the user, even device CALs. Devices are actually very easy to imagine as "workstations" that are alternatively used by one user at a time. Web based applications are multiplexors allowing many users to access a backend service (be it offered by SQL Server or Windows Server) simultaneously.

This is also interesting: http://serverfault.com/questions/13956/active-directory-licensing for popular opinion

Do you have documentation on this? Because I can't verify your statement. Especially since it would appear that a device cal would mitigate this issue.

:) It's shockingly expensive to run Microsoft infrastructures legally but the fact is that any user accesing Windows Server for any service is required to have a Windows Server CAL. This is true regardless of the exact path a user takes to consume the service exposed by Windows Server. In our case, OTRS would act as something that is called multiplexing software, for licensing purposes. That is to say that OTRS intermediates access to the Active Directory Windows Server service for authentication. So you would need one Windows Server CAL for each OTRS user that is registered in Active Directory (agent/customer it doesn't matter). The prices for CALs - and all other licenses - vary wildly based on how many you buy and the way you buy them (retail or volume licensing / subscriptions). There are a couple of specific situations where you don't require a CAL for over-the-Internet-users of web applications hosted on Windows Server. However, AFAIK there are a couple of hooks in those conditions that would catch you so that you require a CAL if the user is not anonymous.

Bottom line is: Microsoft licensing is very very complicated (ensuring you are most likely not perfectly legal ok at all times) and very very expensive.

I think I get what you say and it's also what I've meant. I meant replication as performed by a process / tool independent of OTRS with the purpose of keeping data in customer_user, customer_company tables up to date as dictated by our CRM system. I wasn't assuming any replication capability being built-in OTRS, it would just query the customer data made available to it. Mainly, I was aiming to re-use OTRS's default db client back-end configuration by just switching it in read-only mode and updating client info through a side channel.

I want to avoid switching to a LDAP based customer back-end for as long as possible because we're using Active Directory and our licensing probably doesn't cover including a couple hundred customers in AD. The alternative would be something like OpenLDAP and I expect that to be a bumpy road because non-AD LDAP servers on Windows is not a common occurrence.

BI> possibility of switching the default OTRS db customer back-end in read-only mode That's already possible. Copy the default CustomerUser keys from Defaults.pm to Config.pm and set the ReadOnly flag. (Although it's always this. Not changeable) You can, of course, use a different interface (php? phpmyadmin?) to modify the CustomerUser table but I'd rather sync to something that already can manage this away from OTRS.

Please look at Defaults.pm CustomerUser and read the comments in the information. You can choose to have the whole backend as readonly or only certain fields as readonly.

The CustomerUser Map determines what fields are shown. The comments tell you what fields are necessary. # note: Login, Email and CustomerID needed! # var, frontend, storage, shown (1=always,2=lite), required, storage-type, http-link, readonly, http-link-target, link class(es) var: The variable that is being referenced through the web interface frontend: The label as presented. storage: The field from the data source shown: 1 for always, 2 for lite, 0 for don't show required: 0=no, 1=yes. Don't use 1/Not relevant in read only. storage-type: the examples give var (string) or int. http-link: a URL that wraps this field readonly: 0=no, 1=yes. whether the field can be changed in the web interface http-link-target: for instance, "_blank" (see HTML documentation for targets) link class(es): apparently, optional CSS class to apply to this link. Sometimes this can be used for psuedo classes and Javascript ..

BI> do not change customer_user.login and *.customer_id Query, not sync. just make sure the information is valid in the backend.

BI>generating the password in Windows will probably be a bitch No. CustomerUser is not authentication. It's data. Read this: http://forums.otterhub.org/viewtopic.php?f=60&t=16543
