7. Troubleshooting

7.1. Diagnostic Mode

If module doesn’t work as you expect, it’s worth to enable “Diagnostic Mode”. This will output logs that describes how the module is working. They can also diagnose issues that can occur like: config errors, failed login process, etc. Logs are created in file that is located in ~\Portals\_default\LogsYYYY.MM.DD.logs.resources, see log example below:

_images/troubleshooting-diagnostic-mode_01.png

Logs are created only when plugin is working in “Diagnostic Mode”, to enable it please follow steps below:

  1. Open log4net configuration file DotNetNuke.log4net.config, it can be found in DNN root folder, see figure below:

    _images/troubleshooting-diagnostic-mode_02.png
  2. Inside that file set log level to ALL, see code snippet below:

    <root>
        <level value="ALL" />
        <appender-ref ref="RollingFile" />
    </root>
    
  3. Go to “AD-Pro Azure AD Connector” then “Other Settings” tab and enable option Diagnostic Mode, see figure below

    _images/troubleshooting-diagnostic-mode_03.png
  4. Logging mechanism is turned on, reproduce the sign-in process and check the log file.

7.2. How generate diagnostic logs

Please follow the instructions below on how to generate valuable logs.

  1. First enable diagnostic mode, to do that see instructions from section Diagnostic Mode

  2. Log file is usually very big, which makes it difficult to parse. To remove unncecessary informations, delete log file, before you will reproduce the issue.

    Default path to log file is: ~\Portals\_default\Logs\YYYY.MM.DD.resoures

  3. Reproduce the issue to generate log entries.

  4. Compress log file, and send it to support@glanton.com

7.3. JavaScript issues

7.3.1. Overview

User interface is created at the top of AngularJS framework. JavaScript can be moody although it’s very fast. If you will see interface issues, for example view can’t be loaded or displayed, buttons aren’t responding, it’s worth to check JavaScript errors. Depending what browser you are using, check following articles that are describing how to display these errors in your browser:

If you have any problems with your plugin, please send above error messages to support@glanton.com

7.3.2. Edit & Delete buttons doesn’t work

When you can’t update module settings, and JavaScript throws error like Method Not Allowed... or requests throws 405 HTTP error code, please make sure that WebDAV is disabled. To disable WebDAV, please add following lines to the web.config file, in the section system.webServer-> modules add following line:

<modules>
    <remove name="WebDAVModule"/> <!-- add this -->
    ...
</modules>

in the section system.webServer-> handlers add following line:

<handlers>
    <remove name="WebDAV" />
    ...
</handlers>

the ExtensionlessUrl-Integrated-4.0 handler under the system.webServer-> handlers also applies the verb PUT:

<handlers>
    ...
    <remove name="ExtensionlessUrl-Integrated-4.0" />
    <add name="ExtensionlessUrl-Integrated-4.0" path="*." verb="GET,HEAD,POST,DEBUG,PUT,DELETE" type="System.Web.Handlers.TransferRequestHandler" preCondition="integratedMode,runtimeVersionv4.0" />
    ...
</handlers>

Here you can read more about WebDAV.

7.3.3. View can’t be loaded

If you see situation like on figure below, where only upper part of interface is loaded and instead of bottom part of interface is displayed message Top level state template, probably it’s caused by minified js file.

_images/troubleshooting-javascript_02.png

To fix that issue sign in as DNN host and go to menu “Servers-> Server Settings”. At the bottom is section responsible for reducing Java Script files, please disable Minify JS attribute. See figure below for more info.

_images/troubleshooting-javascript_03.png

7.4. Could not load ‘Microsoft.IdentityModel.Protocol.Extensions’

If error message from figure below appears, disable OWIN pipeline.

_images/troubleshooting-owin_01.png

Usually this message informs about missing librarie(s), in this case it’s Microsoft.IdentityModel.Protocol.Extensions.dll library. Disabling OWIN won’t fix this issue, but at least it should allow start DNN website.

7.5. OwinStartupAttribute

If you get an error message like:

The following errors occurred while attempting to load the app.
- No assembly found containing an OwinStartupAttribute.
- No assembly found containing a Startup or [AssemblyName].Startup class.
To disable OWIN startup discovery,
add the appSetting owin:AutomaticAppStartup with a value of "false" in your web.config.

Same error message is on figure below:

_images/troubleshooting-owin_02.png

This error message is displayed because in web.config file, the OWIN startup library wasn’t declared. To fix that issue please do one of the following:

  • disable OWIN in web.config file by applying code snippet below, see this section for more details:

    <add key="owin:AutomaticAppStartup" value="false" />
    
  • remove GS.AzureADConnector.dll file from DNN bin directory. This will exclude “AD-Pro Azure AD Connector” from DNN, but I hope that your DNN website will start.

7.6. Response status code does not indicate success

When playing with “AD-Pro Azure AD Connector” you can come across some errors. Below are some examples of one and the same error: Unable to get document from.

  • response message with status code 400

  • exception like Response status code does not indicate success

  • below is example of exception stack:

    Response status code does not indicate success: 400 (Bad Request).
    [HttpRequestException: Response status code does not indicate success: 400 (Bad Request).]
    [IOException: Unable to get document from:
    https://login.microsoftonline.com/.well-known/openid-configuration]
    [InvalidOperationException: IDX10803: Unable to create to obtain configuration from:
    'https://login.microsoftonline.com/.well-known/openid-configuration'.]
    
  • print screen with exception

    _images/troubleshooting-status-code-not-success_01.png

This could be raised be the wrong Tenant. Please double make sure that Tenant is correct, and it’s without https:// at the begining.

7.7. Newtonsoft library issue

If you get exception like:

Could not load file or assembly 'Newtonsoft.Json' or one of its dependencies.
The located assembly's manifest definition does not match the assembly reference.
(Exception from HRESULT: 0x80131040)

same error is on print screen below:

_images/troubleshooting-newton-soft_01.png

Check version of Newtonsoft.dll library and corresponding entry in web.config file.

7.8. AADSTS50011: Reply url

If you get error message like:

AADSTS50011: The reply address ‘https://dnn804v2.dev/’ does not match the reply addresses configured for the application: ‘c7b299aa-0abd-4fb5-a5a1-25b22375773d’. More details: not specified

_images/troubleshooting-reply-address_01.png

Please double check Redirect URI in:

  • Azure AD Application,
  • and “AD-Pro Azure AD Connector”,

If you get message like:

AADSTS50011: The reply url specified in the request does not match the reply urls configured for the application: ‘03f6bf15-2f44-4854-96a5-5d1298bdc181’. More details: Reply address did not match because of case sensitivity.

_images/troubleshooting-reply-address_02.png

Double check the case sensitivity of “reply address” specified in DNN “Azure AD Connector” options and “reply address” specified in Azure Application settings.

Section with more info about Redirect URI.

7.9. User or administrator has not consented
