cups 1.2 versus cups 1.4 authentication

[aa]

Hi,

I have cups 1.2 installed and it works. If I upgrade to cups 1.4. I cannot authenticate users. I configure cups to use information provided from LDAP. The users are available and it works with cups 1.2 but with cups 1.4 gives me this error:

cupsdAuthorize: pam_authenticate() returned 7 (Authentication failure)!

Any clue ?

Thanks.
