How to trim a character in Azure AD SAML claims

Question

I have a SAML application which is using emailaddress claim. I have some users who have ' (single quote) in their email addresses and I would like to remove through claim transformations.

For example john.sn**'**ow@google.com should be sent as john.snow@google.com in SAML assertion.

As per the MS official claim transformations article, it may be possible through regexreplace() but the syntax looks so confusing. Can this be achieved at all?

Hi @Akshay

Thanks for reaching out.

You can use the regexReplace() function to transform the mail address.

You can use below regax to remove the single Quote and concatenate the email address.

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

Hope this will help.

Thanks,

Shweta
