Hi Markus
Thank you.
So, do you know, how I have to implement the fallback-mechnism with
squid_ldap_auth?
For instance, if I deny read-rights for the squid-user to the file
/etc/krb5.keytab, I would expect, that the squid_ldap_auth-mechanism
would authenticate the user with a password-prompt. But in my case: A
password-prompt appears (but not the right one....without the correct
realm) and I can enter the correct userid/pw -> no success. If I make
a native basic-authentication with squid_ldap_auth (without
combination with kerberos), then the authentication works fine.
Any hints for the fallback-configuration with squid_ldap_auth? Is
there even a way, to have a fallback-mechanism with squid_ldap_auth?
Thanks a lot.
Kind regards,
Tom
