Problem in get ticket with Kerberos
 
Hello

I have problem for get tickets from kerberos in my Centos 5.2, when I type this command /usr/local/kerberos/bin/kinit admin@LABCOM.UNASP
Show this message

kinit(v5): Cannot resolve network address for KDC in realm LABCOM.UNASP while getting initial credentials

I donīt understand why this message !!! My DNS is work , I can resolve the domain (LABCOM.UNASP)

nslookup labcom.unasp
Server: 192.168.4.66
Address: 192.168.4.66#53

Name: labcom.unasp
Address: 192.168.4.2


My DNS server is on Windows 2003 Server , this command kinit was tested from the server Linux with Centos 5.2 using version keberos 1.6 of MIT , follow I paste kr5b.conf

[libdefaults]
# determines your default realm name
default_realm = LABCOM.UNASP
default_tgs_enctypes = des3-hmac-sha1 des-cbc-crc des-cbc-md5
default_tkt_enctypes = des3-hmac-sha1 des-cbc-crc des-cbc-md5
permitted_enctypes = des3-hmac-sha1 des-cbc-crc des-cbc-md5
kdc_timesync = 1

[realms]
LABCOM.UNASP = {
# specifies where the servers are and on
# which ports they listen (88 and 749 are
# the standard ports)
kdc = kdc.AmbLivre:88
admin_server = kdc.AmbLivre:749
default_domain = labcom.unasp
}

[domain_realm]
# maps your DNS domain name to your Kerberos
# realm name
.labcom.unasp = LABCOM.UNASP
labcom. = LABCOM.UNASP
[kdc]

# logging info
kdc = SYSLOG:INFO:DAEMON
admin_server = SYSLOG:INFO:DAEMON
default = SYSLOG:INFO:DAEMON


and kdc.conf

[kdcdefaults]
v4_mode = nopreauth
