We are getting a weird issue on CM environment.(Sitecore 8.1 update 2)

Pages works fine when direct url is used, but error comes when we try login to sitecore

AppPool recycle solves the issue

Access to the path 'c:\inetpub\wwwroot\cm-prod.npower.com-2016.11.9.1-deployments-2086\sitecore modules\debug' is denied

Log shows above error and some of the times it also shows Access to the path 'C:\inetpub\wwwroot\cm-prod.npower.com-2016.11.9.1-Deployments-2086\sitemaps\' is denied. along with above error

I thought to be permission related issue but folder is not at all there and the issue gets resolved after app pool recycle. Issue comes once in a while (intermittent) but when issue start coming it stays there till app pool is recycled.

App pool identity is set to default app Pool idetity and all folder are set as modify access to IUSR_MachineName

Ading stack trace as I captured it as image when error occured. Stack tracce

Full stack trace given below

Server Error in '/' Application.
________________________________________
Access to the path 'c:\inetpub\wwwroot\cm--2016.11.9\sitecore modules\debug' is denied.
Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code. 

Exception Details: System.UnauthorizedAccessException: Access to the path 'c:\inetpub\wwwroot\cm--2016.11.9\sitecore modules\debug' is denied. 

ASP.NET is not authorized to access the requested resource. Consider granting access rights to the resource to the ASP.NET request identity. ASP.NET has a base process identity (typically {MACHINE}\ASPNET on IIS 5 or Network Service on IIS 6 and IIS 7, and the configured application pool identity on IIS 7.5) that is used if the application is not impersonating. If the application is impersonating via <identity impersonate="true"/>, the identity will be the anonymous user (typically IUSR_MACHINENAME) or the authenticated request user. 

To grant ASP.NET access to a file, right-click the file in File Explorer, choose "Properties" and select the Security tab. Click "Add" to add the appropriate user or group. Highlight the ASP.NET account, and check the boxes for the desired access.

  • can you try to create the /debug directory and set the modify permission for app pool identity? – Andrey Bobrov Nov 15 '16 at 14:51
  • yeah I thought of same work around but wanted to know how come an app pool recycle solves this issue and doing nothing else? – FHN Nov 15 '16 at 15:04

If you are using the Sitecore Azure module for deploying Sitecore solution to Platform-as-a-Service (PaaS) environment (Azure Cloud Services), then the reason of the issue is due to incorrect script that sets permission in the file system:

1

I believe that method instigates the following pipeline:

<speak.client.initialize.layout>
  <processor type="Sitecore.Web.Pipelines.InitializeSpeakLayout.CheckUserAccess, Sitecore.Speak.Client" />
  <processor type="Sitecore.Web.Pipelines.InitializeSpeakLayout.SetDisplayMode, Sitecore.Speak.Client" />
  <processor type="Sitecore.Web.Pipelines.InitializeSpeakLayout.SetAntiForgeryToken, Sitecore.Speak.Client" />
  <processor type="Sitecore.Web.Pipelines.InitializeSpeakLayout.DisableAnalytics, Sitecore.Speak.Client" />
</speak.client.initialize.layout>

You could check that this hasn't been customized (it's normally found in Sitecore.Speak.config).

Looking at the code in those pipelines - if it's not custom code it'll be trying to write the AntiForgeryToken in that folder (it must be the default folder set when you create a new StringWriter).

I'd log this as an issue with Sitecore and create those folders in the interim.

  • It is not Customised :( – FHN Nov 16 '16 at 7:29
  • Is there any chance you could add the full stack trace? Might not help but you never know :) – Owen Niblock Nov 16 '16 at 10:22
  • Added stcak trace as answer beause no option to add image in commnet [![Stack trace][1]][1] [1]: i.stack.imgur.com/FjPWL.png – FHN Nov 16 '16 at 11:28
  • Thanks :) Is there any additional information in the log file? Or does it just repeat the exact same stack trace? – Owen Niblock Nov 16 '16 at 12:18
  • its same .in log..:( – FHN Nov 17 '16 at 5:40

Adding correct user(IIS user) permission to website folder as per Sitecore document solved this issue.

Note:- This answer has been added to solve this issue. Still I am clue less on why an AppPool recycle was able to solve the issue.
