When third-party assemblies try to access some sensitive properties, user code might be blocked. When this issue occurs, “8gaol” event entries are logged in SharePoint Unified Logging System (ULS) logs.
To help maintain security, third-party assemblies are prevented from accessing some sensitive properties.
To resolve this issue, install one of the following updates:
To enable trusted third-party assemblies to access the sensitive properties in the Web.config file, add them to the assembly list.
For example, assume that you find the following message in ULS logs:
8gaol Unable to access this sensitive property : <sensitive property name> from outer untrusted assembly <3rd party assembly full name>. Trusted assembly list: <assembly list for accessing sensitive properties>
In this case, follow these steps:
Add a new AllowAccessSensitivePropertiesAssemblies section under SharePoint SafeMode in the Web.config file:
For each third-party assembly, add an entry that has an assembly full name in the AllowAccessSensitivePropertiesAssemblies section:
<AllowAccessSensitivePropertiesAssembly Assembly="XXX, Version=XXX, Culture=XXX, PublicKeyToken=XXXX"/>
