• Sourcegraph version: 5.3.12303
• Platform information:

We encountered an issue where usernames with suffixes are breaking permissions syncs with Bitbucket, as Bitbucket requires exact username matches. Sourcegraph normalizes usernames by adding a suffix if the username is in email format. This discrepancy affects setups where SCIM and SAML are involved and the username has to be set as an email.

Steps to reproduce:

1. Set up SCIM and SAML with Okta.
2. Create a user and sync permissions with Bitbucket.

Expected behavior:

Usernames should match exactly between Sourcegraph and Bitbucket without normalization issues.

Actual behavior:

Usernames in Sourcegraph get a suffix added during normalization, causing mismatches with Bitbucket usernames.
