[squid-users] Re: squid_kerb_group (again)

Hi Eugene,

  I can only guess that the memory cache is not working. Can you change in
include/autoconf.h

/* Define if kerberos has MEMORY: cache support */
#define HAVE_KRB5_MEMORY_CACHE 1

to

#undef HAVE_KRB5_MEMORY_CACHE

and recompile ?

Hi.

squid 3.3.11
FreeBSD 10.x

I'm fighting squid_kerb_group, sometimes it may become tricky. Here's
where I'm stuck at:

I'm launching this:

===Cut===
KRB5_KTNAME=/usr/local/etc/squid/squid.keytab
export KRB5_KTNAME

/usr/local/libexec/squid/ext_kerberos_ldap_group_acl \
    -a \
    -m 16 \
    -i \
    -ddd \
    -D NORMA.COM \
    -b cn=Users,dc=norma,dc=com \
    -S hq-gc.norma.com_at_NORMA.COM \
    -u proxy2 \
    -p XXXXXXXXXXXXXXXXXXX \
    -N SOFTLAB_at_NORMA.COM \
    -g "Internet Users - Proxy2@"
===Cut===

and getting this:

However, using this keytab and script everything is ok when launching
from another servers.

Some additional info: I can successfully use a ldapsearch with
SASL/GSSAPI bind with this keytab:

Looks like it's really some local problem, but I cannot figure out which
exactly.

Thanks.
Eugene.
