Hint: use Crypt-Password + attribute. You probably don't want to use this module with + FreeBSD to authenticate against system file, as it already takes care + of caching passwd file entries, but it may be helpfull to authenticate + against alternate file. + +Q: Can I use rlm_passwd to authenticate user against SAMBA smbpasswd? +A: Yes, you can. Hint: use LM-Password/NT-Password attribute, set + authtype = MS-CHAP. + +Q: Can I use rlm_password to authenticate user against BLA-BLA-BLApasswd? +A: Probably you can, if BLA-BLA-BLA stores password in some format supported + by RADIUS, for example cleartext, NT/LM hashes, crypt, Netscape MD5 format. + You have to set authtype to corresponding type, for example + authtype = NS-MTA-MD5 + for Netscape MD5. + +Q: Are where are differences between rlm_passwd and rlm_unix? +A: rlm_passwd supports passwd files in any format and may be used, for + example, to parse FreeBSD's master.passwd or SAMBA smbpasswd files, but + it can't perform system authentication (for example to authenticate + NIS user, like rlm_unix does). If you need system authentication you + need rlm_unix, if you have to authenticate against files only under + BSD you need rlm_passwd, if you need to authenticate against files only + under Linux, you can choose between rlm_unix and rlm_passwd, probably + you will have nearly same results in performance (I hope :) ). + +Q: I'm using realms with rlm_passwd. I see rlm_passwd do not strip realm + from user name. How to configure rlm_passwd to strip realm? + +A: In case you configured realm to strip username, User-Password attribute + is not changed. Instead, rlm_realm creates new attribute Stripped-User-Name. + All you need is to use Stripped-User-Name instead of User-Name as a key + field for passwd file. + +Q: How can I say passwd to add attribute even if it's value is empty? + +A: set ignore_empty to "no" in module configuration. + + +5.
