Solution: You must type the principal and policy names in the Name field to work on them, or you need to log in with a principal that has the appropriate privileges.

Per this kerberos keytab introduction: A keytab is a file containing pairs of Kerberos principals and encrypted keys (these are derived from the Kerberos password). You can use http://serverfault.com/questions/446768/error-reading-keytab-file-krb5-keytab this file to log into Kerberos without being prompted for a password. The most common personal use of keytab files is to allow scripts to authenticate to Kerberos without human interaction, or store a password in a plaintext file. This sounds like something we do not need and is perhaps better security-wise to not have it. How can I keep this error from popping up in our system logs? Here is my krb5.conf if its useful: banjer@myhost:~> cat /etc/krb5.conf # This file managed by Puppet # [libdefaults] default_tkt_enctypes = RC4-HMAC DES-CBC-MD5 DES-CBC-CRC default_tgs_enctypes = RC4-HMAC DES-CBC-MD5 DES-CBC-CRC preferred_enctypes = RC4-HMAC DES-CBC-MD5 DES-CBC-CRC default_realm = FOO.EXAMPLE.COM dns_lookup_kdc = true clockskew = 300 [logging] default = SYSLOG:NOTICE:DAEMON kdc = FILE:/var/log/kdc.log kadmind = FILE:/var/log/kadmind.log [appdefaults] pam = { ticket_lifetime = 1d renew_lifetime = 1d forwardable = true proxiable = false retain_after_close = false minimum_uid = 0 debug = false banner = "Enter your current" } Let me know if you need to see any other configs. Thanks. EDIT This message shows up in /var/log/secure whenever a non-root user logs in via SSH or the console. It seems to only occur with password-based authentication. If I do a key-based ssh to a server, I don't see the error. If I log in with root, I do not see the error. Our Linux servers authenticate against Active D

For authentication, i need to use the "GSSAPI" mechanism, not the simple bind. 'simple bind' is working perfectly, but the "GSSAPI" based approach is not working. I am getting the following error whenever i try the "ldapwhoami" command (i ran 'kinit' before running ldapwhoami to make sure i have valid kerberos TGT) ldap_sasl_interactive_bind_s: Local error (-2) additional info: SASL(-1): generic failure: GSSAPI Error: Miscellaneous failure (see text (unable to reach any KDC in realm DEV.EXAMPLE.COM, tried 1 KDC) Please note that the LDAP server and the kerberos server side is working perfectly, means i tested them with things like "ldapsearch", "ldapwhoami" in the centos VM where i have my ldap server + kerberos setup, Its working fine. I am able to see proper output for them. I am getting errors (above error) only when i try the same command from my laptop (client). Note: even i created host principal (host/mymacbook.dev@DEV.EXAMPLE.COM) from my laptop and added it to my local krb5.keytab file using 'kadmin'. Below are my client si
