configuration kerberos in Postgre sql

Hi,

after compling the postgresql --with-krb5 and setting up the krb5-server in
centos, I configured the *postgresql.conf* as bellow:

*krb_server_keyfile = '/var/kerberos/krb5kdc/kadm5.keytab'*
*krb_srvname = 'POSTGRES' * # (Kerberos only)
#krb_caseins_users = off

and

my *pg_hba.conf* is :

# "local" is for Unix domain socket connections only
local all postgres trust
# IPv4 local connections:
host all *frank* 0.0.0.0/0 krb5
#host all all 127.0.0.1/32 trust
# IPv6 local connections:
host all all ::1/128 trust

,and kdc.conf

kdcdefaults]
v4_mode = nopreauth
kdc_tcp_ports = 88

[realms]
EXAMPLE.COM = {
#master_key_type = des3-hmac-sha1
* acl_file = /var/kerberos/krb5kdc/kadm5.acl*
dict_file = /usr/share/dict/words
admin_keytab = /var/kerberos/krb5kdc/kadm5.keytab
supported_enctypes = des3-hmac-sha1:normal arcfour-hmac:normal
des-hmac-sha1:normal des-cbc-md5:normal des-cbc-crc:normal des-cbc-crc:v4
des-cbc-crc:afs3
}

Then, I created the user frank as :

kadmin.local
Authenticating as principal rahimeh/admin(at)EXAMPLE(dot)COM with password.
kadmin.local: * ank frank*
WARNING: no policy specified for frank(at)EXAMPLE(dot)COM; defaulting to no policy
Enter password for principal "frank(at)EXAMPLE(dot)COM":
Re-enter password for principal "frank(at)EXAMPLE(dot)COM":

*kadmin.local: ktadd -k /var/kerberos/krb5kdc/kadm5.keytab frank*
Entry for principal frank with kvno 2, encryption type Triple DES cbc mode
with HMAC/sha1 added to keytab WRFILE:/var/kerberos/krb5kdc/kadm5.keytab.
Entry for principal frank with kvno 2, encryption type ArcFour with HMAC/md5

Entry for principal frank with kvno 2, encryption type DES cbc mode with
RSA-MD5 added to keytab WRFILE:/var/kerberos/krb5kdc/kadm5.keytab.

Finally, it gives error like:

[root(at)localhost ~]# *kinit frank* -t /var/kerberos/krb5kdc/kadm5.keytab
Password for frank(at)EXAMPLE(dot)COM:
*kinit(v5): Password incorrect while getting initial credentials*

or

in cmd when I run this instruction the below error is shown.

[root(at)localhost bin]# ./psql -h 127.0.0.1 -U frank
*psql: krb5_sendauth: Bad application version was sent (via sendauth)*

Please help me.
