Good afternoon,
When attempting to cifs mount (with kerboros security mode) an Isilon
volume from RHEL 7 I get the following error.
-----------
[user@clientbox ~]# mount -t cifs
//isilon.abc.example.com/share123/files /mnt/share123/files -o
username=acoder,password=XXXXXX,sec=krb5
mount error(126): Required key not available
-----------
First, here's my /etc/krb5.conf file:
-----------
[libdefaults]
default_realm = EXAMPLE.COM
dns_lookup_realm = false
dns_lookup_kdc = false
ticket_lifetime = 24h
renew_lifetime = 7d
forwardable = true
[realms]
EXAMPLE.COM = {
kdc = eu.example.com
admin_server = eu.example.com
}
[domain_realm]
.example.com = EXAMPLE.COM
example.com = EXAMPLE.COM
[logging]
default = FILE:/var/log/krb5libs.log
kdc = FILE:/var/log/krb5kdc.log
admin_server = FILE:/var/log/kadmind.log
-----------
where eu.example.com is my organization's AD server.
Next, I show there are no current tickets stored on the client:
-----------
[user@mybox ~]# klist
klist: No credentials cache found (ticket cache FILE:/tmp/krb5cc_0)
-----------
Finally, I try to obtain a ticket using kinit:
-----------
[user@mybox ~]# kinit acoder
kinit: Cannot contact any KDC for realm 'EXAMPLE.COM' while getting
initial credentials
-----------
I'm not showing any additional information in /var/log/messages or
/var/log/krb5libs.log
1) Am I heading in the right direction?
2) If so, am I missing something from my krb5.conf file? What else do
I need to check?
