OK, I had LDAP 'working' but radiusd -X was showing the old 'WARNING: No "known good" password was found in LDAP' errors. Ignoring much of the 'wisdom' on other sites to just ignore the error, I'm trying to squash all errors from the -X output. It was failing because the bind failed (due to a bad 'identity' line in the ldap module config), thus it didn't find a userPassword from LDAP, causing PAP to be skipped but since I had the 'ldap' module in the authenticate section of the sites file, it attempted to bind with the username/password supplied from the NAS to the ldap directory which worked, thus Accept-Accept was given. To correct the bind problem, I added an ACL to the directory to allow 'uid=admin,o=radtree' to access the userPassword attribute, then configured the ldap module to use 'uid=admin,o=radtree' as the identity and 'secret' as the password. Now the bind succeeds, the -X output says that it's mapping userPassword -> Crypt-Password == "{crypt}4gOgBZqZgtwIw" (if I bind to the directory and search as uid=admin,o=radtree for the testuser account, the userPassword returned (after base64 decoding) is {crypt}4gOgBZqZgtwIw. If I run 'testpassword' with a salt of '4g' through the crypt(3) subroutine, I get '4gOgBZqZgtwIw', so the directory contains the correct password), I have "checkItem Crypt-Password userPassword" in the dictionary for this ldap module. Anyway, I'm still seeing one of the 'No "known good" password' errors and PAP is failing because the passwords don't match, and I'm not sure where the problem lies (obviously, the passwords don't match, but _why_). It looks like I'm getting the correct encrypted password back from the directory, and PAP is reporting a login attempt with the correct password....
