Christopher,

Yes, I have. Please see below.

# cat krb5.conf
libdefaults]
       default_realm = COMPANY.COM
	default_keytab_name = /etc/krb5/krb5.keytab
	default_tkt_enctypes = arcfour-hmac-md5 des-cbc-crc des-cbc-md5
	default_tgs_enctypes = arcfour-hmac-md5 des-cbc-crc des-cbc-md5
	allow_weak_crypto = true

[realms]
     COMPANY.COM = {
               kdc = ads.company.com:88
               admin_server = ads.company.com
		default.domain = COMPANY.COM
               kpasswd_server = ads.company.com
       }

[domain_realm]
	.company.com = COMPANY.COM
	company.com = COMPANY.COM
# 


# kinit -k sapldap/ads.company.com at COMPANY.COM
kinit(v5): Key table entry not found while getting initial credentials
# 

When I use it without -k option, it works and prompts for password and only takes correct password.
klist shows recent date and expiration time.
