When you try to connect to Amazon Redshift data source from Spotfire Analyst, if the password contains special characters, then the following error might occur:

It is a known defect with Redshift connector if password contains any of the following special characters:

• @
• %
• }
• {
• +
• ;
• <space>

As a workaround, remove the above mentioned special characters from the password to make this work.

This issue is addressed in hotfix 10.3 HF-012, 10.8 and onwards. It will connect to Redshift if the password contains any of these characters: [ % , { , } ,+ , ; ,<space>].

Note that @ character cannot be used due to limitations in Redshift. 

 Although some exceptions have already been mentioned in the Redshift documentation. Following is the extract from the same:
 

"It can be any printable ASCII character (ASCII code 33 to 126) except ' (single quotation mark), " (double quotation mark), \, /, @, or space".

Password authentication fails while connecting to Amazon Redshift using the Spotfire connector if the password contains special characters.
