ntlm_auth problem using EAP-TLS with MSCHAP authentication toLDAP server

[Clement Ogedengbe]

No...  I don't have any of such definition .. However,  I can see the
following when Radius started ..

rlm_ldap: LDAP lmPassword mapped to RADIUS LM-Password
rlm_ldap: LDAP ntPassword mapped to RADIUS NT-Password
rlm_ldap: LDAP sambaLmPassword mapped to RADIUS LM-Password
rlm_ldap: LDAP sambaNtPassword mapped to RADIUS NT-Password
rlm_ldap: LDAP dBCSPwd mapped to RADIUS LM-Password

You have either Cleartext-Password or NT-Password defined in your LDAP  
database, haven't you?


If not, see:

Have a nice day!
