Failure unspecified at GSS-API level (Mechanism level: Checksum failed) One of the classics The password is wrong. The attempt to look up the IP address of the local host failed. It's believed to be related to Active Directory cross-realm/forest stuff, but there are hints that it can also be raised when the kerberos client is trying to auth with a KDC, Minor code may provide more information (Unknown code krb5 195) This can happen if you simply have not done a kinit if you are working from the command line.

When this problem occurs, the following error is generated: ERROR: CLI error trying to establish connection: [SAS/ACCESS][ODBC SQL Server Wire Protocol driver]Security Services Error: Unspecified error at the GSS layer. : Your process was issued with a ticket, which has now expired. The timestamps of the systems are out of sync, so it looks like an old token be re-issued. We have thousands of customers today integrating GSSAPI enabled applications with AD, leveraging Centrify.

Therefore check to make sure that the credential cache created with kinit is the one the Python LDAP GSSAPI call is trying to use. Your machine has a hostname, but the service principal is a /_HOST wildcard and the hostname is not one there's an entry in the keytab for. I can succesfully read AD/Centrify objects using the module using a simple bind [IE username/password] but object reading after the keytab is initialised [instead of a simple authentication] in the process The kerberos principal has to match the FQDN of the LDAP server.

It is a network problem being misinterpreted as a Kerberos problem, purely because it surfaces in security code which assumes that all failures must be Kerberos related. 2016-04-06 11:00:35,796 ERROR org.apache.hadoop.hdfs.server.datanode.DataNode: This time your Kerberos ticket has expired. Even if the service is not logged in. I found http://aput.net/~jheiss/krbldap/howto.html very good.

  • You should make sure that the user your Python script is running as is the user that has obtained a Kerberos ticket with kinit or you can setup the environment variable
  • Oracle describe the JRE's handling of version numbers in their bug database.

  • I am not a Python person (nor a programmer) so I would not even dive into the intricacies of using GSSAPI calls inside of it.

I have documented here, not a step by step guide, but a list of the issues I have faced configuring Kerberos to work with LDAP when things don't go the way http://crimsonskysoftware.com/unspecified-error/unspecified-error-qtp-11.html GSS initiate failed —no further details provided WARN ipc.Client (Client.java:run(676)) - Couldn't setup connection for [email protected] to / org.apache.hadoop.ipc.RemoteException(javax.security.sasl.SaslException): GSS initiate failed at org.apache.hadoop.security.SaslRpcClient.saslConnect(SaslRpcClient.java:375) at org.apache.hadoop.ipc.Client$Connection.setupSaslConnection(Client.java:558) This is widely agreed to

The fix: add the short name of the host to /etc/hosts.

In particular, they are usually some generic IOException wrapping a generic security exception. Despite rebulding the module from source and pointing it to the centrify ldap libs I can not get GSS / keytab authentication working with python ldap.Interestingly I also tried a perl See Trademarks or appropriate markings. Type adsiedit.msc and click OK.

Root causes should be the same as for the other message. However, the advise has been consistent - make sure you have it working at the OS level before going into Python-LDAP. Your keytab contains an old version of the keytab credentials, and cannot parse the information coming from the KDC, as it lacks the up to date credentials. check over here The time limit of a negotiated token for the HTTP connection has expired.

That is: you have a TGT, it's just for the wrong realm. All rights reserved. If they say "Don't go there", it'll be based on experience of fielding those support calls and from having seen the Active Directory source code. This can be useful if you are phasing in a new CA certificate and/or LDAP server certificate.

that FS instance is unauthenticated. Renewal failed for some other reason. When you see this assume network connectivity problems, or something up at the KDC itself. Please tell us how we can make this article more useful.

If it's a physical cluster, make sure that your NTP daemons are pointing at the same NTP server, one that is actually reachable from the Hadoop cluster. Locate the entry for the web server you are trying to browse to that has an HTTP Service Type. The ldapsearch binary that is included with our package can do an AD bind using the computer's account credentials (because we maintain a keytab for the computer object), that is because Use ktlist -kt to list the entries in each keytab.

Also the LDAP server needs to know where this keytab file is. This example shows why errors reported as Kerberos problems, be they from the Hadoop stack or in the OS/Java code underneath, are not always Kerberos problems. GSSException: No valid credentials provided (Mechanism level: Fail to create credential. (63) - No service creds) Rarely seen. Your error is that the Python GSSAPI ldap bind is not finding the credential cache.
