rlm_pap(5)							 FreeRADIUS Module							rlm_pap(5)

NAME

       rlm_pap - FreeRADIUS Module

DESCRIPTION

       The  rlm_pap  module  authenticates RADIUS Access-Request packets that contain a User-Password attribute.  The module should also be listed
       last in the authorize section, so that it can set the Auth-Type attribute as appropriate.

       When a RADIUS packet contains a clear-text password in the form of a User-Password attribute, the rlm_pap module may be used for  authenti-
       cation.	The module requires a "known good" password, which it uses to validate the password given in the RADIUS packet.  That "known good"
       password must be supplied by another module (e.g. rlm_files, rlm_ldap, etc.), and is usually taken from a database.

CONFIGURATION

       The only relevant configuration item is:

       auto_header
	      If set to "yes", the module will look inside of the User-Password attribute for the headers {crypt}, {clear}, etc., and  will  auto-
	      matically create the appropriate attribute, with the correct value.

       This module understands many kinds of password hashing methods, as given by the following table.

       Header	    Attribute	       Description
       ------	    ---------	       -----------
       {clear}	    Cleartext-Password clear-text passwords
       {cleartext}  Cleartext-Password clear-text passwords
       {crypt}	    Crypt-Password     Unix-style "crypt"ed passwords
       {md5}	    MD5-Password       MD5 hashed passwords
       {smd5}	    SMD5-Password      MD5 hashed passwords, with a salt
       {sha}	    SHA-Password       SHA1 hashed passwords
       {ssha}	    SSHA-Password      SHA1 hashed passwords, with a salt
       {nt}	    NT-Password        Windows NT hashed passwords
       {x-nthash}   NT-Password        Windows NT hashed passwords
       {lm}	    LM-Password        Windows Lan Manager (LM) passwords.

       The  module  tries  to  be  flexible  when  handling  the various password formats.  It will automatically handle Base-64 encoded data, hex
       strings, and binary data, and convert them to a format that the server can use.

       It is important to understand the difference between the User-Password and Cleartext-Password attributes.  The Cleartext-Password attribute
       is  the "known good" password for the user.  Simply supplying the Cleartext-Password to the server will result in most authentication meth-
       ods working.  The User-Password attribute is the password as typed in by the user on their private machine.  The two are not the same,  and
       should  be  treated  very differently.  That is, you should generally not use the User-Password attribute anywhere in the RADIUS configura-
       tion.

       For backwards compatibility, there are old configuration parameters which may be work, although we do not recommend using them.

rlm_mschap(5)							 FreeRADIUS Module						     rlm_mschap(5)

NAME

       rlm_mschap - FreeRADIUS Module

DESCRIPTION

       The rlm_mschap module provides MS-CHAP and MS-CHAPv2 authentication support.

       This module validates a user with MS-CHAP or MS-CHAPv2 authentication.  If called in Authorize, it will look for MS-CHAP Challenge/Response
       attributes in the Acess-Request and adds an Auth-Type attribute set to MS-CHAP in the Config-Items list unless Auth-Type has already set.

       The module can authenticate the	MS-CHAP  session  via  plain-text  passwords  (User-Password  attribute),  or  NT  passwords  (NT-Password
       attribute).  The module cannot perform authentication against an NT domain.

       The  module  also enforces the SMB-Account-Ctrl attribute.  See the Samba documentation for the meaning of SMB account control.	The module
       does not read Samba password files.  Instead, the fIrlm_passwd module can be used to read a Samba password file, and supply an  NT-Password
       attribute which this module can use.

       The main configuration items to be aware of are:

       authtype
	      This is the string used to set the authtype.  Normally it should be left to the default value of MS-CHAP.

       use_mppe
	      Unless this is set to 'no', FreeRADIUS will add MS-CHAP-MPPE-Keys for MS-CHAPv1 and MS-MPPE-Recv-Key/MS-MPPE-Send-Key for MS-CHAPv2.
	      The default is 'yes'.

       require_encryption
	      If MPPE is enabled, setting this attribute to 'yes' will cause the MS-MPPE-Encryption-Policy attribute to be set to require  encryp-
	      tion.  The default is 'no'.

       require_strong
	      If MPPE is enabled, setting this attribute to 'yes' will cause the MS-MPPE-Encryption-Types attribute to be set to require a 128 bit
	      key.  The default is 'no'.

       with_ntdomain_hack
	      Windows clients send User-Name in the form of "DOMAINUser", but send the challenge/response based only on the User  portion.   Set-
	      ting this value to yes, enables a work-around for this error.  The default is 'no'.
