MWS 10.5 , latest fixes

Licensed

What are trying to achieve? Please describe in detail.

I have configured the LDAP Kerberos configuration in my MWS. Have done all the steps mentioned in the SAG documentation but looks like it’s not working.

When I am trying to login through browser it shows blank page and in the MWS log I can see the message like trying to login as guest user and authentication fails

Do you get any error messages? Please provide a full error message screenshot and log file.
