Hi,
From your log file I also see that squid_kerb_ldap is crashing. Can you

need to debug it to find the reason for the crash in free().
Regards
Markus

Can you add the option -d -i to squid_kerb_auth and squid_kerb_ldap to
create more debut output and send the cache.log extract

Hi Henrik/Markus/All
Every setting(keeping in view your recommendation) was correct i many a
times confirmed that.Even i tried re-creating the SPN but in vain. However
i
just realized that most of the users were required to logoff and login to
get authenticated through squid. I wonder why a user even with a valid TGT
was require to do that as he should be able to get the TGS for every new
kerberized service???
Anyways of the few users i tried only one was able to access it without
re-login. Bottom line is that its working.
Now the authorization portion is not seems like behaving properly can you
please check the syntax for correctness before i probe further. I have
appended at the bottom my squid.conf portion relevant to this.
e.g. After the authorization few of the clients were showing this wheter
in
the group or not:
--------------------------------------------------------------
Internet explorer cannot display the webpage
what you can try:
Diagnose connection problems
More Info
--------------------------------------------------------------
Further i think IE7(and latest) and FireFox 3.6.x above are supportive for
kerberos. Am i right? is there any special configuration required on the
client side(other than the proxy settings).??

Make sure the squid servers hostname matches squidhr1.v.local. If not
use -s
HTTP/squidhr1.v.local as an option to squid_kerb_auth.

Hi all,
I am unable to do kerberos authentication in my live enviroment as appose
to
the test enviroment where it was successful. My environment is Active
Direcory Single Forest Multidomain with each domain having multiple
domain
controllers.
SPN was created through:
msktutil -c -b "OU=UNIXOU" -s HTTP/squidlhr1.v.local -h
squidlhr1.v.local -k
/etc/squid/HTTP.keytab --computer-name squid-http --upn
HTTP/squidlhr1.v.local --server ldc-ms-dc2.v.local --verbose
Through ADSIEDIT & setspn tools SPN is confirmed in the Active Directory.
My kerb5.conf Settings:
[libdefaults]
default_realm = MAILSERVER.V.LOCAL
dns_lookup_realm = false
dns_lookup_kdc = false
default_keytab_name = /etc/krb5.keytab
; for windows 2003 encryption type configuration.
default_tgs_enctypes = rc4-hmac des-cbc-crc des-cbc-md5
default_tkt_enctypes = rc4-hmac des-cbc-crc des-cbc-md5
permitted_enctypes = rc4-hmac des-cbc-crc des-cbc-md5
[realms]
V.LOCAL = {
kdc = ldc-v-dc2.v.local
admin_server = ldc-v-dc2.v.local
}
MAILSERVER.V.LOCAL = {
kdc = ldc-ms-dc2.mailserver.v.local
admin_server = ldc-ms-dc2.mailserver.v.local
}
# BT.V.LOCAL = {
# kdc = dc.bt.v.local
# admin_server = dc.bt.v.local
#}
[domain_realm]
.linux.home = MAILSERVER.V.LOCAL
.v.local = V.LOCAL
v.local = V.LOCAL
.mailserver.v.local = MAILSERVER.V.LOCAL
mailserver.v.local = MAILSERVER.V.LOCAL
#.bt.v.local= BT.V.LOCAL
#bt.v.local = BT.V.LOCAL
[logging]
kdc = FILE:/var/log/kdc.log
admin_server = FILE:/var/log/kadmin.log
default = FILE:/var/log/kdc.log
I have tried this on multiple client computers but not seem to be
working....
