Azure AD Claim Transformation RegEx Replace Remove Character

Question

Hi All,

I am having an issue trying to get this RegEx Replace to work.

We need to remove hyphens and apostrophes from user's email address when sending a SAML Claim. This is a limitation on the vendor's part to ingest hyphens and apostrophes.

If a user has a hyphen or apostrophe in their email address, it needs to be removed when sending the claim.

Example Email Claim: ******@company.com

Expected Transform Claim / Output: BobSacamentoWilliams

Current Settings:

Transformation: RegExReplace ()

Attribute: user.mail

Regex Pattern: (?'mail'^.*?)(?i)(@.*)$

Replacement Pattern: {mail}

I am not sure where to use [^-'] in the RegEx Pattern portion to extract everything except the hyphen and apostrophe. Microsoft does not appear to be using any syntax that makes sense from other websites.

Answer 1

Hi @JonBoi ,

Apologies for delay in response.

You can use below regex to

^(?'firstpart'[^']+)-(?'Hyphen')|(?'lastpart'[\w\.-]+@[\w\.-]+)$

to remove the hyphen from the email address.

Hope this will help.

Thanks,

Shweta
