Problem TTLS-LDAP

14 Jun 2005

      Hi, everybody!

I have a problem on having tried to use TTLS with
LDAP. I have seen solutions to this problem in this
mailing list, but I have not had success.

In the following line it seems that ldap realizes
correctly the comparison:
....
rlm_ldap: user prueba authorized to use remote access
....

 but after that error  comes:
....
rlm_ldap: Attribute "User-Password" is required for
authentication.
  modcall[authenticate]: module "ldap" returns invalid
for request 0
modcall: group Auth-Type returns invalid for request 0
auth: Failed to validate the user.
....

Please, if someone have an idea to solve it, I will be
grateful  very much.

I attach my configuration files and the complete
result of the execution.

Thanks
