This article clarifies that regular expressions (RegEx) used within Identity Provider routing rules are case-sensitive.

• Identity Provider routing rules

RegEx used in Identity Provider routing rules is case-sensitive. This design means that any character entered in uppercase or lowercase is treated as a distinct character.

For example, if a RegEx is created to match a user's email address against the string example@email.com, it will only match if the email address provided by the user exactly matches this string, including capitalization.

• The values Example@email.com or example@EMAIL.com will not produce a match.

• Blank spaces are also treated as distinct characters. Any discrepancy, such as an extra space or a letter in the wrong case, will cause a mismatch.

Therefore, it is important to ensure that RegEx expressions are configured with the correct casing to function as intended.
