Email Alerts are not received...

In one of application, Email alerts are sent using SQL sp_send_dbmail stored procedure. Email alerts were working properly, but suddenly noticed email alerts are not received.

To troubleshoot the issue, first I checked the msdb.dbo.sysmail_event_log table using the below query.

SELECT log_id, event_type, log_date, description, process_id, mailitem_id, account_id, last_mod_date, last_mod_user
FROM
msdb.dbo.sysmail_event_log 
ORDER BY
log_date DESC

If there is any error, you should see records with the event_type value as error.
In my case there are records with event_type value as error, and the description value for those records is same as below

The mail could not be sent to the recipients because of the mail server failure. (Sending Mail using Account 3 (2018-02-01T10:41:27). Exception Message: Cannot send mails to mail server. (The SMTP server requires a secure connection or the client was not authenticated. The server response was: Authentication required).  )

As per the error descript…

Multiple Roles - Different Dimensions in SSAS Security is not impossible...

We had a requirement to implement dynamic security in SSAS with multiple roles for different dimensions.
But due to the Additive design of SSAS security, it is causing issues and people think that is impossible.
But I found the below useful link, which mentioned some of the alternative approaches.

Actually to have multiple roles for different dimensions, you need to consider below scenarios

If you allow access in one role, you need to restrict that in the other roles.Need to consider the scenario that the user is not belongs to any of the roles and restrict access in that scenario as well.Also make sure that you put the tick for the Enable Visual Total check box in the security applied attribute. Instead of the custom assembly approach mentioned in the above link, I was able to get done the same using a reference table and have that as a Non-Additive fact in the cube.
As an example let say …
