What are the allowed special characters for the User ID field (user_field) for SSO users?

[Rain Vaine]

Hello experts,

We encountered an issue wherein some of the special characters for the user_id is not allowed for SSO login and causes error.  An example is the "%" sign. Do anyone of you have any idea about the documentation or resource regarding this topic.

Thanks,

I would recommend you to please connect with your SSO identity provider who can exactly tell you the allowed characters for the user identifiers.

Hello,

Thanks for the reply but the main problem is seen without trying first with connecting via sso. When you create a user with a user id containing % sign for example, it is save in the record but you cannot login using that user id.

Hi,

User name can contain Alpha [A-Za-z] Numeric value [0-9] with limited special characters "[@-_.]"
