Thanks for the answer. It works. i put them into PATH, so now i don't get an error : sh: wbinfo: command not found but i still have: /etc# wbinfo_group.pl mylan\test Use of uninitialized value in concatenation (.) or string at /usr/local/squid/libexec/wbinfo_group.pl line 35, <STDIN> line 1. Use of uninitialized value in concatenation (.) or string at /usr/local/squid/libexec/wbinfo_group.pl line 39, <STDIN> line 1.

ERR When i start squid i really can make authentication with acl lists on groups: as i show in my first question. But why I receive such messages from wbinfo_group.pl Regards, Nikolay blymn@xxxxxxxxxxxxxxxxx@inet 07.02.2005 13:43 To nikolay.nenchev@xxxxxxxxxxxxxxxxxxxxxxx cc squid-users@xxxxxxxxxxxxxxx Subject Re: [squid-users] nt domain ntlm group authentication problem?

Either modify wbinfo_group.pl and specify the full path for the wbinfo executable or make sure the directory that holds wbinfo is set in PATH before squid is executed. -- Brett Lymn
