−Status
+
−======
+
−
+
−libnss-mysql-bg was installed at Savannah and configured against the
+
−old Savane MySQL database.  It works :)  This means we can avoid
+
−reimplementing sv_users, as well as a part of sv_groups.
+
−
+
−Next step is converting the libnss-mysql.cfg file to the new Savane DB
+
−schema.
+
−
+
−libnss-mysql is an alternative, but it's less flexible, since you can
+
−only configure fields instead of complete SQL queries.
+
−
+
−libnss-mysql-bg has 2 annoying bugs:
+
−
+
−- When listing users or groups, it may skip large entries. Report:
+
−  http://sourceforge.net/tracker/?func=detail&aid=2833844&group_id=56073&atid=479258
+
−
+
−- The list of group members is implemented inefficiently (1 MySQL
+
−  query per group).  This is mainly a problem when listing groups, but
+
−  so a real problem when authenticating.  Solution suggested at:
+
−  http://lists.gnu.org/archive/html/savannah-hackers-public/2009-08/msg00004.html
+
−
+
−For sanity we should fix those bugs.  However, if libnss-pgsql is
+
−better, we could just move to PostgreSQL.

−Segfault FAQ
+
−============
+
−
+
−- Check /var/log/syslog - maybe you just got an error in your SQL
+
−  query.
+
−
+
−- Check that the svusers group is present (libnss-mysql-bg dislikes
+
−  NULLs).
