+.TH rlm_passwd 5 "20 January 2015" "" "FreeRADIUS Module"
+.SH NAME
+rlm_passwd \- FreeRADIUS Module
+.SH DESCRIPTION
+The \fIrlm_passwd\fP module provides authorization via files similar
+in format to /etc/passwd.
+.PP
+This module allows you to retrieve any account information from any
+files with passwd-like format (/etc/passwd, /etc/group,
+smbpasswd, .htpasswd, etc). Every field of the file may be mapped to
+a RADIUS attribute, with one of the fields used as a key.
+.PP
+The module reads the file when it initializes, and caches the data in
+memory.  This makes it very fast, even for files with thousands of
+lines. To re-read the file the module will need to be reloaded with
+\fIradmin(8)\fP, or the server will need to be sent a SIGHUP, as
+dynamic updates are not supported.
+.PP
+.SH CONFIGURATION
+The configuration item(s):
+.IP allow_multiple_keys
+If set to 'yes', and more than one record in file matches the request,
+then the attributes from all records will be used. If set to 'no' (the
+default) the module will warn about duplicated records.
+.IP delimiter\ =\ ":"
+The character to use as a delimiter between fields.  The default is
+":"
+.IP filename
+The path to the file.
+.IP format
+The format of the fields in the file, given as an example line from
+the file, with the content of the fields as the RADIUS attributes
+which the fields map to. The fields are separated by the ':' character
+in the configuration (no matter what is configured for the 'delimiter'
+option).
+.IP hash_size
+The size of the hash table. A larger value means less probability of a
+collision so records will be found faster, at the expense of greater
+memory usage. Having a hash_size in the range of 30-100% of the number
+of passwd file records is reasonable.
+.IP ignore_empty
+When set to "yes", the default, empty fields in the input will be
+skipped and the RADIUS attribute will not be added.  By setting this
+value to "no", all attributes in the format list will always be added,
+even if they have no value.
+.IP ignore_nislike
+If set to 'yes', then all records from the file beginning with the '+'
+sign will be ignored.  The default is 'no'.
+.PP
+.SH FORMAT
+The \fIformat\fP option controls how lines are read from the file, and
+which fields are mapped to which RADIUS attributes.
+.PP
+The key field is the field being searched for within the file. It is
+normally signified by being preceded with a '*' character, which
+indicates that the field has only one key, like the /etc/passwd file.
+The key field may instead be preceded with '*,', which indicates that
+the field has multiple possible comma-separated keys, such as when
+searching the /etc/group file.
+.PP
+The other fields signify RADIUS attributes. By default they will be
+added as a control attribute list.
+.PP
+To add an attribute to the RADIUS request (as though it had been sent
+by the NAS), prefix the attribute name in the "format" string with the
+\(aq~' character.
+.PP
+To add an attribute to the RADIUS reply (to be sent back to the NAS),
+prefix the attribute name in the "format" string with the '='
+character.
+.PP
+.SH EXAMPLES
+.DS
+format = "*User-Name:Crypt-Password:"
+.DE
+.IP
+For a file the looks similar to /etc/passwd. The first field,
+User-Name, is the key to look up in the file. When the record is
+found, a control attribute, 'Crypt-Password', will be added with the
+contents of the second field. (Note this will not work with shadow
+passwords.)
+.PP
+.DS
+format = "My-Group:::*,User-Name"
+.DE
+.IP
+Parse a file similar to the /etc/group file.  An entry matches a
+request when the name in a User-Name attribute exists in the
+comma-separated list of a line in the file.  When an entry matches, 
+a "My-Group" attribute will be created and added to the control
+items for the request.  The value of that attribute will be taken from
+the first field of the matching line in the file.
+.IP
+The ":::" in the format string means that there are extra two fields
+in the line, in between the group name and list of user names.  Those
+fields do not map to any RADIUS attribute, and are therefore ignored.
+.IP
+For this example to work in practice, you will have to add the
+My-Group attribute to the dictionary file.  See \fIdictionary(5)\fP
+for details on how this may be done.
+.PP
+.DS
+format = "~My-Group:::*,User-Name"
+.DE
+.IP
+Similar to the previous entry, except the My-Group attribute is added
+to the request, as though it was sent by the NAS.
