Hi, i have problem with wbinfo_group.pl srcipt and group authentication. My ntlm and basic authentication is working fine, using samba.3.0.10 and squid-2.5. i have compiled squid with : --enable-auth=ntlm,basic --enable-external-acl-helpers=wbinfo_group --enable-snmp. cp /usr/localsamba/bin/wbinfo /usr/local/squid/libexec/ /usr/local/squid/libexec# ls -la total 752 drwxr-sr-x 2 squid squid 4096 Feb 7 09:22 . drwxr-sr-x 9 squid squid 4096 Feb 7 09:24 .. -rwxr-xr-x 1 squid squid 95429 Feb 2 08:57 cachemgr.cgi -rwxr-xr-x 1 squid squid 117468 Feb 2 08:57 unlinkd -rwxr-xr-x 1 root squid 527498 Feb 7 09:22 wbinfo -rwxr-xr-x 1 squid squid 1333 Feb 2 08:57 wbinfo_group.pl domain: mylan user: test when i start: ./wbinfo_group.pl mylan\test Use of uninitialized value in concatenation (.) or string at ./wbinfo_group.pl line 35, <STDIN> line 1. sh: wbinfo: command not found sh: wbinfo: command not found Use of uninitialized value in concatenation (.) or string at ./wbinfo_group.pl line 39, <STDIN> line 1.
