+.Sh DESCRIPTION
+The Auto Blacklist module for PAM,
+.Nm
+provides functionality for only one PAM category: authentication.
+In terms of the
+.Ar module-type
+parameter, this is the
+.Dq Li auth
+feature.
+.Ss Auto Blacklist PAM Authentication Module
+.Nm
+provides auto blacklisting of hosts and users responsible for repeated
+failed authentication attempts. Generally configured so that blacklisted
+users still see normal login prompts but are guaranteed to fail to
+authenticate.  This functionality is only available to services which call
+PAM as root.  If
+.Nm
+is called for uid != 0 it will silently succeed.
+
+The following options may be passed to the authentication module:
+.Bl -tag -width indent
+.It Cm debug
+.Xr syslog 3
+debugging information at
+.Dv LOG_DEBUG
+level.
+.It Cm expose_account
+Ignored.
+.It Cm no_warn
+suppress warning messages to the user.
+These messages include reasons why the user's authentication attempt was
+declined.
+.It Cm try_first_pass
+Ignored.
+.It Cm use_first_pass
+Ignored.
+.It Cm use_mapped_pass
+Ignored.
+.It Cm config Ns No = Ns Ar config-file
+The configuration file contains additional arguments. In order for the
+.Nm
+blacklist maintenance tool to work correctly most of the configuration
+should be placed in the config file rather than being provided by arguments.
+The format of the config file is described below.
+.It Cm host_db Ns No = Ns Ar host-database-file
+Path to the Berkeley DB which is used to log the host responsible for failed
+authentication attempts.
+If host_db is omitted the corresponding auto blacklisting will be disabled.
+.It Cm host_purge Ns No = Ns Ar time
+Defines how long failed hosts are retained in the host database.
+Defaults to 1 day.
+.It Cm host_rule Ns No = Ns Ar host-rule
+The rule (see below for format) which defines the conditions under which a
+failed hosts will be blackisted.
+.It Cm user_db Ns No = Ns Ar user-database-file
+Path to the Berkeley DB which is used to log the user responsible for failed
+authentication attempts.
+If user_db is omitted the corresponding auto blacklisting will be disabled.
+.It Cm user_purge Ns No = Ns Ar time
+Defines how long failed users are retained in the user database.
+Defaults to 1 day.
+.It Cm user_rule Ns No = Ns Ar user-rule
+The rule (see below for format) which defines the conditions under which a
+failed users will be blackisted.
+.El
+.Ss Rules syntax
+.Cm host_rule No Cm user_rule
+are the rules which determine the circumstances under which accounts ares
+auto blacklisted.
+The
+.Cm host_rule
+is used to block access to hosts that are responsible for excessive
+authentication failures and the
+.Cm user_rule
+is used to disable accounts for which there have been excessive
+authentication failures.
+Each rule consists of a number of space separated
+.Sy user clauses Ns No .
+A
+.Sy user clause
+specifies the user names and services to match and a set of triggers.
+A simple example would be:
+.Bd -literal -offset indent
+*:10/1h
+.Ed
+.Pp
+which means 'block any user (*) if they are responsible for ten or more
+failed authentication attempts in the last hour'.
+In place of the '*' which matches any user a list of usernames can be
+supplied like this:
+.Bd -literal -offset indent
+root|dba|admin:10/1h
+.Ed
+.Pp
+which means 'block the users root, dba and admin if they are responsible
+for ten or more failed authentication attempts in the last hour'.
+You can also specify a service name to match against like this:
+.Bd -literal -offset indent
+root/sshd|dba/*:3/1d
+.Ed
+.Pp
+which means 'block the users root for service sshd and user dba for any
+service if they are responsible for three or more failed authentication
+attempts in the last day'.
+Finally you can specify multiple triggers like this:
+.Bd -literal -offset indent
+root:10/1h,20/1d
+.Ed
+.Pp
+which means 'block the user root if they are responsible for ten or more
+failed attempts in the last hour or twenty or more failed attempts in the
+last day.
+.Pp
+Multiple rules can be provided separated by spaces like this:
+.Bd -literal -offset indent
+*:10/1h root:5/1h,10/1d
+.Ed
+.Pp
+in which case all rules that match a particular user and service will be
+checked.
+The user or host will be blocked if any of the rule triggers matches.
+.Pp
+The sense of the user matching can be inverted by placing a '!' in front
+of the rule so that:
+.Bd -literal -offset indent
+!root:20/1d
+.Ed
+.Pp
+is a rule which would match for all users apart from root.
+.Pp
+It is important to treat root as a special case in the
+.Cm user_rule
+otherwise excessive attempts to authenticate as root will result in the
+root account being locked out even for valid holders of root credentials.
+.Pp
+Here is the full syntax for rules:
+.Bd -literal -offset indent
+word ::= /[^\\s\\|\\/\\*]+/
+name ::= word | '*'
+username ::= name
+servicename ::= name
+userservice ::= username | username '/' servicename
+namelist ::= userservice | userservice '|' namelist
+userspec ::= namelist | '!' namelist
+multiplier ::= 's' | 'm' | 'h' | 'd'
+number ::= /\d+/
+period ::= number | number multiplier
+trigger ::= number '/' period
+triglist ::= trigger | trigger ',' triglist
+userclause ::= userspec ':' triglist
+rule ::= userclause | userclause /\s+/ rule
+.Ed
+.Pp
+For rules to work correctly
+.Cm host_purge No and Cm user_purge 
+must be at least as long as the longest period specified in a corresponding
+rule.
+You may wish to retain information about failed attempts for longer than
+this so that the 
+.Nm
+blacklist maintenance tool can report information over a longer period of
+time.
+The format for this items is a number with an optional multiplier suffix,
+'s', 'm', 'h' or 'd' which correspond with seconds, minutes, hours and days.
+To specify seven days for example one would use '7d'.
+Note that in normal operation
+.Nm
+PAM module will only purge the logged data for a particular host or user
+if it happens to be updating it, i.e. if that host or user makes another
+failed attempt.
+To purge all old entries the 
+.Nm
+blacklist maintenance tool should be used.
+.Ss Blacklist maintenance tool
+Blacklist maintenance tool
+.Nm
+perform maintenance on the databases used by the
+.Nm
+PAM module.
+The options are as follows:
+.Bl -tag -width indent
+.It Fl h | Fl -help
+Print help page and exit.
+.It Fl p | Fl -purge
+Purge databases according to purge rules in config.
+.It Fl r | Fl -relative
+Display times relative to now otherwise absolute times will be displayed.
+.It Fl v | Fl -verbose
+Verbose output.
+.It Fl -okhost Ns No = Ns Ar host-name
+Unblock host.
+.It Fl -okuser Ns No = Ns Ar user-name
+Unblock user.
+.It Ar config-file
+Name of the
+.Nm
+configuration file (default: %%ETCPREFIX%%/etc/pam_abl.conf).
+The config file is read to discover the names of the
+.Nm
+databases and the rules that control purging of old data from them.
+.El
+.Sh EXAMPLES
+.Ss Auto Blacklist PAM module
+Typically
+.Nm
+PAM module is added to the auth stack as a required module just before
+whatever modules actually peform authentication.
+Here's a fragment of the PAM config:
+.Bd -literal -offset indent
+auth required   pam_env
+auth required   pam_abl  config=%%ETCPREFIX%%/etc/pam_abl.conf
+auth sufficient pam_unix likeauth nullok
+auth required   pam_deny
+.Ed
+.Ss Blacklist maintenance tool
+Obtain a list of failed hosts and users:
+.Bd -literal -offset indent
+$ pam_abl
+.Ed
+.Pp
+Obtain a full list of failures listing times relative to now:
+.Bd -literal -offset indent
+$ pam_abl -rv
+.Ed
+.Pp
+Purge old data:
+.Bd -literal -offset indent
+$ pam_abl -p
