Hi There,
I have an openldap master (hosted by server) and an openldap replica (hosted by replica). Authentication use SASL/GSSAPI with kerberos.
On the master i get the following output : server:~ admin$ kinit root Please enter the password for root@SERVER.LAN: server:~ admin$ ldapsearch -b cn=mounts,dc=server,dc=lan SASL/GSSAPI authentication started ldap_sasl_interactive_bind_s: Other (e.g., implementation specific ) error (80)
What does your /etc/ldap.conf and ~/.ldaprc look like?
You might try adding a '-d -1' to your ldapsearch command for additional debugging information.
With the debug i get the following message
res_errno: 80, res_error: <SASL(-1): generic failure: GSSAPI Error: Unspecified GSS failure. Minor code may provide more information (Key table entry not found)>, res_matched: <>
(Remark : As information i provide the entire debug at the end of this message)
Because of the message "keytable entry not found", i tried to use kadmin and check if principle with root exists. But by using kadmin i get now this message :
server:~ admin$ kadmin -p root@SERVER.LAN Couldn't open log file /var/log/krb5kdc/kadmin.log: Permission denied Authenticating as principal root@SERVER.LAN with password. Password for root@SERVER.LAN: kadmin: Communication failure with server while initializing kadmin interface server:~ admin$
I check the logfile owner, group owner, and permission. Then i compared with one other kerberos server. Permission and owner was different. I set permission identically. But nothing was changed.
With kadmin.local i checked and root@SERVER.LAN exists in the list.
So it looks more a kerberos issues than a ldap one.
Regards,
