Bug Fixes

Fixed the mTLS Proof-of-Possession token cache to key on the certificate's full DER (x5t#S256) instead of only the public key, preventing a stale token (and AADSTS500181) after a same-key certificate renewal. #6123
Fell back to RS256 when a certificate's PSS signing operation is rejected by RSACryptoServiceProvider, rebuilding the client assertion so authentication can proceed. #6126
Detect and reject symbolic links in the Unix cache-file write path (lstat pre-check plus O_NOFOLLOW), closing a TOCTOU window. #6115
Corrected misleading "region required" error messages and doc comments in the mTLS PoP flow. #6127
