I had this problem too.

Check your authentication subsystems configuration. You probably set the next option:

[font=Courier]alfresco.authentication.allowGuestLogin=false[/font]

In alfresco-authentication.properties. By default this file is here:

[font=Courier][size=12]$TOMCAT_HOME/webapps/alfresco/WEB-INF/classes/alfresco/subsystems/Authentication/alfrescoNtlm/[/size][/font]

Or here:

[font=Courier][size=12]$TOMCAT_HOME/shared/classes/alfresco/extension/subsystems/Authentication/alfrescoNtlm/[/size][/font]

If you did things correctly.

As I can see, you have configured [font=Courier]passthru[/font] and [font=Courier]ldap-ad[/font] authentication subsystems so maybe these options could cause this error message too:

[font=Courier]passthu.authentication.guestAccess=false
ldap.authentication.allowGuestLogin=false[/font]

Check if you changed these settings in the files passthru-authentication-context.properties and ldap-ad-authentication.properties.

They should be in the next directories:

[font=Courier][size=12]$TOMCAT_HOME/shared/classes/alfresco/extension/subsystems/Authentication/passthru/
$TOMCAT_HOME/shared/classes/alfresco/extension/subsystems/Authentication/ldap-ad/[/size][/font]

In my case, I modified default value and only when I changed it back to:

[font=Courier]alfresco.authentication.allowGuestLogin=true[/font]

This error message disappeared from logs.

Looking for its cause, I found the file restrictions.get.desc.xml in:

[font=Courier][size=12]$TOMCAT_HOME/webapps/alfresco/WEB-INF/classes/alfresco/templates/webscripts/org/alfresco/repository/admin/[/size][/font]

As you can see in its content:


<webscript>
  <shortname>Alfresco Repo Restrictions</shortname>
  <description>Get repository restrictions</description>
  <url>/api/admin/restrictions</url>
  <format default="json" />
  <authentication>guest</authentication>
  <transaction allow="readonly">required</transaction>
  <family>Admin</family>
  <lifecycle>internal</lifecycle>
</webscript>
‍‍‍‍‍‍‍‍‍‍‍‍

Authentication option is set as guest. This value specifies that at least guest authentication is required to execute this web script. Anyhow, you should be able to change this option without breaking normal execution. It didn't fail in previous versions of Alfresco.

What I can confirm is that this error hasn't been logged anymore since I changed this setting.

Please, could you confirm if you solve the problem making these changes?

Same for me (v4.2d): when GuestLogin disabled, my log get a lot of "Authentication failed for Web Script org/alfresco/repository/admin/restrictions.get" error. When GuestLogin enabled, no more error messages.

Any idea of what I should do (of course, I don't want to keep guest login enabled).
Thanks in advance,

Vincent
