So what happened to the good old anonymous authentication is RS 2005? The short answer is that it is no longer supported. There were good technical reasons: anonymous accounts (the IUSER_* and IWAM_* accounts) are managed by windows security system. We decided not to trot into that space, nor did we want to add a new configuration setting for anonymous accounts, and having to manage the username and password of the anonymous user account. This may seem like a flop, but think about it from another angle: why would you want everyone on the internet to be able to view/update/overwrite your stuff on the report server?
With so little said about best practices, I shouldn't really be telling people how to enable anonymous authentication. So here is the disclaimer again:
DO NOT USE ANONYMOUS AUTH!
NEVER USE IT IN PRODUCTION ENVIRONMENT!
But if you are still undeterred, thinking you have a super secure environment and your servers are never exposed to malicious users, here is the solution for the reckless :). This is an adaptation of the RS Forms auth sample, so the easiest thing to do is to replace code in the sample with the code at the bottom of this blog post.
· Change authentication mode in rereportserver.config to “Custom”:
<Authentication>
<AuthenticationTypes>
<Custom/>
</AuthenticationTypes>
<EnableAuthPersistence>true</EnableAuthPersistence>
</Authentication>
· Change auth mode in report server and report manager web.config file to “None”. Set impersonation property to “false”:
<authentication mode="None" />
<identity impersonate="false"/>
· Compile the code below into Microsoft.Samples.ReportingServices.AnonymousSecurity.dll .
· Drop Microsoft.Samples.ReportingServices.AnonymousSecurity.dll into report server bin folder (e.g. D:\Program Files\Microsoft SQL Server\MSRS10.MSSQLSERVER\Reporting Services\ReportServer\bin)
· Add the extension to rereportserver.config file:
<Security>
<Extension Name="None" Type="Microsoft.Samples.ReportingServices.AnonymousSecurity.Authorization, Microsoft.Samples.ReportingServices.AnonymousSecurity" />
</Security>
<Authentication>
<Extension Name="None" Type="Microsoft.Samples.ReportingServices.AnonymousSecurity.AuthenticationExtension, Microsoft.Samples.ReportingServices.AnonymousSecurity" />
</Authentication>
· Configure code access security. Add the following into rssrvpolicy.config. Since my project had no strong name, I used url membership:
<CodeGroup
class="UnionCodeGroup"
version="1"
PermissionSetName="FullTrust"
Name="Private_assembly"
Description="This code group grants custom code full trust. ">
<IMembershipCondition
class="UrlMembershipCondition"
version="1"
Url="D:\Program Files\Microsoft SQL Server\MSRS10.MSSQLSERVER\Reporting Services\ReportServer\bin\Microsoft.Samples.ReportingServices.AnonymousSecurity.dll"
/>
</CodeGroup>
· Restart report server and now you have anonymous authentication.
