Hello @Menakabm,
do you have Single Sing On configured in your web applications?
Are you using an LDAP or AD account, or internal SAS account to log in.
Perhaps the account is not there in the metadata, or the SSO authentication does not work.
I would like to advise to check the SAS Metadata server log files, the SASLogon web application log files, looking for errors.
And theck the Accounts tab in your SAS metadata user, in SAS Management COnsole.
If you cannot or we cannot find anything, I would advise to check the problem with SAS Technical Support.
