Alan,

Your pointer to the MS-CHAP issue with usernames got me thinking.  I looked closely at 
the logs and one machine was sending usernames in lowercase, and the other was sending 
them partially upper-cased (which, after some research, i found they were in our 
Active Directory with some characters capitalized for some reason =/ ).  After 
changing the user in AD to have an all-lowercase name just as they are in our 
OpenLDAP, the problem laptop is able to login.

This doesn't explain why one laptop would lowercase the username before 
authenticating, but I don't think that is anything I'll ever understand.

Thanks for the help.

Alan,

Upon setting "with_ntdomain_hack = no", of course now my wireless users cannot be 
found in ldap, so the systems that did work before do not now:

radius_xlat:  '(uid=MNU.EDU\\Matt)'
radius_xlat:  'dc=mnu,dc=edu'
ldap_get_conn: Got Id: 0
rlm_ldap: performing search in dc=mnu,dc=edu, with filter (uid=MNU.EDU\\Matt)
rlm_ldap: object not found or got ambiguous search result
rlm_ldap: search failed
ldap_release_conn: Release Id: 0
  modcall[authorize]: module "ldap" returns notfound for request 25

It looks to me like the domain is not used in the calculation of ms-chap, otherwise it 
would not work at all when using with_ntdomain_hack, or am I missing something?


I'll do a packet dump and come back with the results.

  If one works and the other doesn't, then the ONLY difference is in
the RADIUS requests.  Compare the RADIUS requests from the two laptop
authentications, and see what's different.  The differences are
breaking authentication.

  See a post earlier today on the list.  MS-CHAP depends on
usernames.  "with_ntdomain_hack = yes" means that the user name is
changed, so MS-CHAP authentication will NOT work.

  Try setting "with_ntdomain_hack = no"
