Issue/Introduction

• Deploying an Embedded vCenter Server Appliance 6.7 or an External Platform Services Controller 6.7 to an Existing SSO domain fails displaying the following error message:

Failed to validate sso.(log_info() takes 1 positional argument but 2 were given)

Cause

This issue occurs due to a syntax error in the sso-cli.py utility that was introduced in vSphere 6.7.

Resolution

This issue is resolved in vCenter Server 6.7.0c.

Workaround:

Correct the syntax error in sso-cli.py with the steps below on the vCenter Server Appliance after stage 1,

1. Log into the bash shell as root. For more information, see the Enable and Access the Bash Shell from the Appliance Shell section of the vCenter Server Appliance Configuration Guide.
2. Create a backup of the sso-cli.py utility. 

cp /opt/vmware/share/htdocs/vami/backend/sso-cli.py /tmp/sso-cli.py

4. Change the sso-cli.py utility to be writable. 

chmod 744 /opt/vmware/share/htdocs/vami/backend/sso-cli.py

5. Edit the sso-cli.py utility to correct the syntax error on line 82.

From:
vami.log_info("Ignoring non-IP/DNS subjectAltName " "extension: '%s'", ext_str)

To:
vami.log_info("Ignoring non-IP/DNS subjectAltName "
            "extension: '%s'" % ext_str)

where the second line is indented from the first line by 12 spaces.

Note: For more details on editing see Editing files on an ESX host using vi or nano.  

6. Revert the changes in step 3 to make the sso-cli.py utility read-only.  

chmod 444 /opt/vmware/share/htdocs/vami/backend/sso-cli.py
