Hello Ivan
Problem still persists. What do you mean by the {crypt} header. These
are simple /etc/passwd file converted into a ldif database using LDAP
Migration Scripts from padl.com
This is what the logs look like
(supplied clear text passwd - from
radtest)
rlm_ldap: bind as uid=try,ou=People,dc=example,dc=com/trialanderror to
30.0.0.2:389
rlm_ldap: waiting for bind result ...
rlm_ldap: Bind failed with invalid credentials
++[ldap1] returns reject
auth: Failed to validate the user.
Found Post-Auth-Type Reject
+- entering group REJECT
expand: %{User-Name} -> try
attr_filter: Matched entry DEFAULT at line 11
++[attr_filter.access_reject] returns updated
Thanks
Sambuddho
