auth: If passwd-file can't be read, return tempfail (not user unknown).

global: unsigned int:1 -> bool:1 perl -i -pe 's/unsigned int ([^,:;]+):1;/bool $1:1;/' **/*.[ch]

auth: passwd-file now stat()s the file max once per second. It's quite unnecessary to do it more often.

Hash table API is now (mostly) type safe.

auth: if passwd-file isn't the only userdb, don't complain about missing userdb fields

auth: Fixed using same passwd-file with different username_format settings. --HG-- branch : HEAD

Implemented support for listing all users in userdb. --HG-- branch : HEAD

Changed .h ifdef/defines to use <NAME>_H format. --HG-- branch : HEAD

Added username_format parameter for passwd-file passdb and userdb. --HG-- branch : HEAD

Allow empty uid/gid fields, they're required if we want to set extra fields for passdb. Also removed some unused code. --HG-- branch : HEAD

If passwd-file is being used as userdb, complain immediately if some entries don't have userdb information. Also some other cleanups and crashfix for today's earlier changes. --HG-- branch : HEAD

Updated passwd-file format to allow specifying any key=value fields. Since the value fields may contain ':' characters, this changes the file format a bit. Previously the last two fields were "flags" and "mail". Flags has been empty for last 3 years however, so the new format is used if the flags field contains something. In that case there is no separate mail field, it can instead be specified by adding userdb_mail=<mail> parameter. --HG-- branch : HEAD

If debug is enabled, tell how many users are found from passwd-file whenever it's read. --HG-- branch : HEAD

deinit, unref, destroy, close, free, etc. functions now take a pointer to their data pointer, and set it to NULL. This makes double-frees less likely to cause security holes. --HG-- branch : HEAD

Added "bool" type and changed all ints that were used as booleans to bool. --HG-- branch : HEAD

Separated passdb_module's interface and the actual data struct. Now it's possible to have multiple passdbs of same type but with different settings. --HG-- branch : HEAD

Added support for variables in passwd-file path. --HG-- branch : HEAD

Logging changes. Make sure we don't write control characters to log and also log IP address. --HG-- branch : HEAD

Chrooting changes. Now all userdbs will support "<chroot>/./<homedir>" style home directories. --HG-- branch : HEAD

passwd-file fixes. passdb ignores now fields after password, so it can work with shadow-like file. --HG-- branch : HEAD

Added default_pass_scheme to LDAP. Support for more password schemes. Merged password checking code with LDAP and passwd-file, so both support the same schemes now. --HG-- branch : HEAD

Cleanups, LDAP support compiles again and generally looks ok, even if it doesn't necessarily work :) Works now with new master config. --HG-- branch : HEAD
