Technical Tip: How to reduce the generated IdP prefix in order to allow for more than 16 IdPs/Domains

Steps to decrease the IdP prefix to increase the IdP/domain count:

1. Add SP by going to Authentication -> SAML IdP -> Service Providers and selecting 'Create New'.

2. Input all relevant information.

    

3. For 'IdP Metadata', select the plus sign.

4. Select 'Random' and a 16-character prefix is populated.

5. Limit is 255 (alphanumeric (26 + 10)) characters. 

   As such, for 16 16-character prefix, it is possible to make 16 domains. Ensure all prefixes are unique.

    

6. Decrease this to as low as 3 to be able to get the most out of the 255 limit. 2 or lower, and not so many unique combinations are getting.

    

This process is also applicable for manually creating the IdP prefix. Simply do not do step 4.
