I have a kerberos client and following is the config of that client for logging.
[logging]
default = FILE:/var/log/krb5kdc.log
admin_server = FILE:/var/log/kadmind.log
kdc = FILE:/var/log/krb5kdc.log
however when I check the files to see the logs it doesn't exist. Even if I try to authenticate with wrong username it shows the error message on console only.
kinit -kt gaurang.shah.keytab gaurang.shah#ab.com
kinit: Keytab contains no suitable keys for gaurang.shah#ab.com while getting
initial credentials
Could someone please let me know what I need to do in so that all the error messages are redirected to log file. Also, is there any way to change verbose of the logs ?
This configuration is not intended for the client as you can see by the filenames. You are looking for KRB5_TRACE=/path/to/file env var. This works on MIT Kerberos only.

We have setup weblogic 12.2.1.4 clustered environment with 2 nodes in a cluster. We use session ID as part of authentication mechanism to log our user session info to the database. When both managed servers are up, the server generates this session ID:
MrvgJEMe6NG95XNsflnhsWjspl52GXPdl33whbIfGkgaEQm7Rk0X!1974917613!-533469515!1605782630842
When we tried to test session replication, by bringing down the server that currently serves the HTTP request, we have noticed that the session ID has changed and contains NONE as part of the generated ID.
MrvgJEMe6NG95XNsflnhsWjspl52GXPdl33whbIfGkgaEQm7Rk0X!1974917613!NONE!1605782630842
This has caused session replication inconsistency. Has anyone encountered the same issue and how did you resolve it? Your inputs are highly appreciated.
Thank you in advance for the help.
Enable the Debug Flags to Track Session Replication Failures
To gather more logging information about session replication failures, you should enable the flags DebugCluster, DebugClusterAnnouncements, DebugFailOver, DebugReplication, and DebugReplicationDetails.
To Enable:
In WebLogic Server 9.x and higher, the reccommended approach is to use the admin console. For each server in the domain, navigate to Servers -> -> Debug and enable the desired flag(s).
You can use the weblogic.Admin command line utility to dynamically turn the debug options on and off.
For example, to turn on DebugCluster on all administration instances of ServerDebug Mbean (i.e., Admin Server or a Managed Server):
java weblogic.Admin -url t3://localhost:7001 -username system -password weblogic SET -type ServerDebug -property DebugCluster true
Alternatively, you can edit the config.xml and the Mbean element in the stanza for each server that you want to debug and set the value to "true" to enable or "false" to disable. Then you must restart the Admin Server. Managed Servers will reconnect to the Admin Server and the debug flags will then dynamically take effect. Example:
At the end, with all the flags set, in your config.xml the ServerDebug tag would like below:
Make sure the stdOutSeverity level of the server is INFO and StdoutDebugEnabled is set to "true". The debug information will be logged into the server log as well as to the standard out.
Validate the Weblogic.xml entries
Make sure weblogic.xml has all the parameters that need to be set for each Session Replication type. For example, when using in-memory replication the sample weblogic.xml would look like:
I faced the below error when importing t24 applications in design studio. The T24 server (TAFJ R18) which I try to connect to is up (jboss is running), but still I face this issue:
Unable to fetch data from T24. Check your connection details and if T24 is up and running.
Subroutine:
Return Code: FAILURE
Response size: 1
Response 1 ->Response Code: EB-SECURITY.VIOLATION,Response Type: NON_FATAL_ERROR,Response Text: Please check your Login Credential and/or access rights,Response Info: 98748ebf-f73d-4e86-8506-950b2fd0b5d2,
Looks like the Username and Password you have provided in the t24-server/config/server.properties is not correct. Make sure you can login to T24 (Browser or Classic) with the T24 User provided in these settings:
#T24 User name used for introspection and deployment (TAFJ)
username=INPUTT
#T24 Encrypted password used for introspection and deployment (TAFJ)
password={encoded}gXhuXZkbBuL09T8WFlRR+w==
Other important settings in this file:
#T24 host name to connect to (IP address or Domain name)
host=localhost
#T24 Web service (TAFJ) port number to connect
ws.port=8080
#Protocol: ftp, sftp or local (TAFC & TAFJ: used for *.b and *.d file transfer)
protocol=ws
#context for web-service
context=axis2
We can check the connectivity and also if anyone restarting the jboss while importing.
We can check the server status is "active" in DS, or we can restart the server connectivity.
And make sure if you are using any VPN to connect the Database and still it is active.
I need to enable SSO on my redhat environment. I need to know which rpms needs installation.
believe it’s a case of configuring AD to support the single sign-on against the WebSeal instance.i am installing WebSeal 6.1(Tivoli Access Manager WebSeal 6.1).
I have no knowledge regarding this.Can anyone brief me out and help me here how to proceed and what steps should be taken. What should be the prerequisites ?
There is a good writeup on IBM's InfoCenter about how to do this:
TAM 6.0:

You have to:
Install IBM Kerberos client for WebSEAL
Create an entry in AD for the Linux server to auth against
Map the Kerberos principal to that AD user (the hardest part)
Enable SPNEGO on WebSEAL
Here are some of my notes that may help. However, I would strongly recommend walking down through the instructions on the InfoCenter site, as they are almost right on.
For step 1, in the linux_i386 directory, install the IBM Kerberos client using:
rpm -i IBMkrb5-client-1.4.0.2-1.i386.rpm
For step 2, the ktpass command you run on your AD controller should look something like:
ktpass -princ HTTP/WEBSEAL_SERVER_NAME_NOTFQDN#ad-domain.org -pass new_password -mapuser WEBSEAL_SERVER_NAME_NOTFQDN -out c:\WEBSEAL_SERVER_NAME_NOTFQD_HTTP.keytab -mapOp set
Transfer that keytab file to your Linux server.
Also make sure the keytab file on the Linux server is chown ivmgr.ivmgr; chmod 600. Otherwise the WebSEAL process won't be able to read it.
For step 3, you will need to edit /etc/krb5/krb5.conf and configure the KDC, AD realm, and local DNS name. You can use the mkkrb5clnt utility to help with this:
config.krb5 -r AD-DOMAIN.ORG -c ad-domain.org -s ad-domain.org -d AD-DOMAIN
Edit krb5.conf and change:
[libdefaults]
default_tkt_enctypes = des-cbc-md5 des-cbc-crc
default_tgs_enctypes = des-cbc-md5 des-cbc-crc
From my notes, I had you can test the Kerberos configuration using (this is all documented on the infocenter article):
/usr/krb5/bin/kinit webseal#AD-DOMAIN.ORG
Enter the password for the WebSEAL user, then use klist to check things.
For step 4, just edit the WebSEAL config file and change:
[spnego]
spnego-auth = https
[authentication-mechanisms]
kerberosv5 = /opt/PolicyDirector/lib/libstliauthn.so
If you are clients are configured correctly, as long as their AD account name matches their TAM account name then it will work. You can also have WebSEAL prepend the #DOMAIN.ORG when mapping to a TAM user, which is handy if you are going to have multiple domains setup for SSO. However, you have to have TAM accounts with user#domain.org within your directory to map to.
You can specify what auth level SPNEGO comes in by modifying the [authentication-levels] section in the WebSEAL config file. That level would be level = kerberosv5
Good luck and have patience. Getting the Kerberos client setup on the Linux box was the most difficult part. It's a bit tricky when it wants capital DNS domain name, lower case DNS domain name, or just the plain vanilla AD domain name.
I'm trying to read out (later maybe even write) into a Google Spreadsheet with Net::Google::Spreadsheets.
The most boilerplate script dies with "Login failed" and no error:
use Net::Google::Spreadsheets;
my $service = Net::Google::Spreadsheets->new(
username => 'myusername#googlemail.com',
password => 'mypassword'
);
All I'm getting is
Net::Google::AuthSub login failed
Sadly, I don't know how one would diagnose or fix this issue. Anyone?
Thanks so much!
May be because of SSL certificate checking. You can skip the test with:
$ENV{PERL_LWP_SSL_VERIFY_HOSTNAME} = 0;
Though really you should set the certificate authorities correctly, as per the message returned by the Net::Google::AuthSub module:
Can't verify SSL peers without knowing which Certificate Authorities
to trust
This problem can be fixed by either setting the PERL_LWP_SSL_CA_FILE
envirionment variable or by installing the Mozilla::CA module.
To disable verification of SSL peers set the
PERL_LWP_SSL_VERIFY_HOSTNAME envirionment variable to 0. If you do
this you can't be sure that you communicate with the expected peer.
I am using JBoss 4.x application server. I am trying to login to the JMX console which requires authentication.
I am providing username and password as "admin" but still it gives as HTTP 401.
Following entry is present in my jmx-console-users.properties file
# A sample users.properties file for use with the UsersRolesLoginModule admin=JBossAdmin.
I assume that the last part of this line is actually a line by itself:
# A sample users.properties file for use with the UsersRolesLoginModule
admin=JBossAdmin
If that's the case, then the username is admin and the password is JBossAdmin . If not, it means the file doesn't contains any username/password. Just create a line similar to the one I mentioned above. Also, please promise me that you'll not leave admin as password.
