SAS Metadata Server reports an authentication error in the following two scenarios.

Scenario 1

SAS Metadata Server 9.4 might fail to start and the log file (SAS-configuration-directory\Lev1\SASMeta\MetadataServer\Logs\SASMeta_MetadataServer_date_nodename_pid.log) reports the following messages at the end of the file:

The error occurs because the SAS-configuration-directory\Lev1\SASMeta\MetadataServer\adminUsers.txt file contains a user with CAS or cas as the Active Directory/LDAP domain. For example, you might encounter the error if the adminUsers.txt file looks similar to the following:

It is important to note that this SAS Metadata Server start-up error might occur during a deployment of SAS^® 9.4, because the SAS^® Deployment Wizard temporarily updates the adminUsers.txt file with the SAS Installer User account. If this account contains a CAS or cas as the domain, then the deployment might fail.

Scenario 2

A second scenario in which a similar error might occur is when the following two conditions are met:

• The adminUsers.txt file does NOT contain a user with CAS or cas as the domain. In other words, you use the default adminUsers.txt file. In this case, SAS Metadata Server starts up normally and without error.
• A logon is attempted from a client application such as SAS^® Management Console or SAS^® Enterprise Guide^® using a user ID with CAS or cas as the domain. Here is an example user ID: cas\user-ID

In this scenario, the error reported to the client application includes this message:

The error reported to the metadata server log looks similar to the following:

Workaround

The workaround for the issue is to remove the user containing a domain of CAS or cas from the adminUsers.txt file. Then, you must change the name of the Active Directory/LDAP domain to something other than CAS or cas.
