Compilation Notes

  • Microsoft Windows: NDB Cluster did not compile correctly using Visual Studio 2022. (Bug #35967676)

Pluggable Authentication

  • Beginning with this release, the behavior of the AUTHENTICATION_PAM_LOG environment variable used in debugging the PAM authentication plugin is changed as follows:

    • Setting AUTHENTICATION_PAM_LOG to an arbitrary value (except as noted in the next item) no longer includes passwords in its diagnostic messages.

    • To include passwords in the diagnostic messages, set AUTHENTICATION_PAM_LOG=PAM_LOG_WITH_SECRET_INFO.

    For more information, see PAM Authentication Debugging. (Bug #74313, Bug #20042010)

Bugs Fixed

  • In limited cases, passing data to the MD5() encryption function could halt the server. (Bug #35764496)
