Hi,
Just want to confirm if Centrify is affected by SambaCry.
We have a few hundred RHEL machines with some Samba stand-alone installed on it but not enabled. We are planning to uninstall Samba altogether. My concern are the following:
1. Wil Centrify be affected by uninstalling Samba in the machines
2. Is Centrify affected by SambaCry
3. If yes, do we have any patch?
I hope you can direct to the resources here. Thanks in advance
After installing the Centrify Smart Card Assistant, it insert my smart card but the cert goes into a different keychain in the Apple keystore... I was using Java to access my Apple Keystore but none of the certificates installed by the Smart Card Assistant were accessible by Java.
I have an EC2 box where we have multiple docker containers running (say 10 containers for example).
These containers are created from same docker image. Centrify installation and AD Group join is already configured on EC2 box, which means an user needs to provide their "Single Sign On" credentials in order to login to EC2 box.
Situation in hand:
We want to create 1 Docker container per user environment. This mean each user will have their own dedicated docker container. 1 centrify user shouldn't be able to login to 2nd centrify user docker container.
For this we have ceated a custom shell script & placed it inside /usr/local/bin (/usr/local/bin/custom_usr_shell). Permission of custom_usr_shell script is 777.
cat /usr/local/bin/custom_usr_shell
#!/bin/bash
container_name=$(logname)
docker start $container_name
docker exec -it $container_name /bin/bash
We want to run this custom shell (/usr/local/bin/custom_usr_shell) when any centrify user logins to EC2 box because custom script on execution will enable a centrify user to directly go inside their docker container rathr than default /home/<user> location.
Issue being Faced:
Followed instructions abut modifying the shell for all users OR single user but issue still exists.Refer to http://community.centrify.com/t5/Centrify-Express/how-to-change-user-shell/td-p/17480
Option 1: Modify shell for all users. Performed below with no success.
Modified /etc/centrifydc/centrifydc.conf & changed "# auto.schema.shell: /bin/bash" line to
"auto.schema.shell: /usr/local/bin/custom_usr_shell", followed by adreload & adflush.
Option 2: Modify shell for single user. Performed below as well with no success.
Created passwd.over file with below contents.
cat /etc/centrifydc/passwd.ovr
+user_id:::::::/usr/local/bin/custom_usr_shell
+:::::::
chmod 644 /etc/centrifydc/passwd.ovr
adreload
adflush
Error Message when user tries to login:
Could not chdir to home directory /home/<user_id>: Permission denied
DirectAudit was run as -centrifyda and determined that the real executable to run is /usr/local/bin/custom_usr_shell, however /usr/local/bin/cdax/custom_usr_shell does not seem to exist, or the current user does not have appropriate execute permissions to start it. Please contact your administrator to either replace /usr/local/bin/custom_usr_shell with a known good shell binary (for instance: from media, backups or network), modify the execute permissions on /usr/local/bin/custom_usr_shell, or to manually disable auditing. Note that as auditing for -centrifyda is currently broken, it is recommended that you avoid execution of any scripts which are interpreted by -centrifyda.
DirectAudit tries to maintain a backup copy of the default system shell, while this shell is not currently available, you may be able to mount the appropriate filesystem to retrieve and use that copy in recovery operations. Copies are kept in the following locations: /usr/share/centrifydc/bin/da.emergency.shell and /etc/centrifyda/da.emergency.shell
Connection to xx.xxx.xx.xx closed.
We are trying to login with single account on around 100's to 1000's of servers in timeframe of 15-20mins(ID used for triggering few stuffs related to application in repeated intervals after successful login). During the time able to see nearly 30-40% of servers are showing as account locked out for the ID when attemping to login, but rest 60% are successful logins.
When checked in Active Directory, account is not locked out and its successful on rest of the servers mentioned.
When we try to rerun on the failed servers, it will be again successful after some time. Also, servers and ID are in same domain, no cross domain authentication or servers here.
Hence, not sure why its setting it flag as locked on few servers?
Also is there restriction of single user ID login for larger set of servers in defined timeframe, say only 100 servers single user can login in 10mins or kind of creteria defined from Centrify end?
Too many hours trying to make this work. I am willing to learn, it can't be this hard.
I completed the install, and it appears to be connected to the DC

Hello,
In MFA, is it possible to send verification email to another (common) mailbox, instead of the primary email address associated with the mailbox?
Why am asking this is because, since the authentication email will be sent to the primary email address (the one I am accessing now), it will go into a cyclical loop and you I not be able to login to the mailbox at all. This will negate the use of Multi-Factor Authentication (MFA), where someone wants to access the mailbox even when browsing outside the corporate network.

Hi Everyone,
One of our user is not able to couple of hosts using his AD ID. I was able to see his ID on those hosts,but still not able to login. He is able to login to other hosts with the same password.
Below are the logs generated in /var/adm/messages when he try to login.

Hello,
We have setup the Centrify connector in two domains. In one domain, it was working fine.
In other domain, we have created one user account in a sub OU recently. This account is not updated in Centrify portal. Hence, it is not automatically proceeding without asking for password. It is logging into the portal as if it is cloud ID.
Can you please tell us how to resolve this issue?

Hi,
I am completely new to Centrify software. The most obvious question I have is how do I install the Agent, when the agent is names:
centrify-suite-2017.1-rhel4-x86_64.solitairetheme8.
I was expecting to see a .tgz file or rpm package to install the Agent. How do I install this on a redhat platform?.
Could you please advise why the naming of the agent is .solitairetheme8.
Regards
Patrick McHale
Just a simple question. Does Centrify Express on a RedHat 7.3 system support SmartCard authentication? I see that MAC has a free SmartCard utility, hoping RedHat 7.3 does too.
Does any one know how to query the email of a user's manager from the Manger attribute in Active Directory?
I am using the Provisioning script editor. By using manager = source.Get('manager'); I am able to get the Manger's CN (CN=Manger's LastName\, FirstName,OU=SomeOU,OU=DOMAIN,DC=com). Is there a way to query the email of the manager?
hi,
I am trying to connect our Ubuntu laptops to an AD instance running on the cloud. Currently it is "Simple AD".
http://docs.aws.amazon.com/directoryservice/latest/admin-guide/directory_simple_ad.html
While checking and joining the domain are all fine, it is not able to recognize the user and not able to login as an AD user. In some other posts I saw it may not work with non-MS ADs and hence let me first check if Centrify Express is compatible with Simple AD.
If it is compatible, please see what the problem is. Here are some details.

# adquery user vikram
vikram is not a zone user
# adquery user vikram -A
returns lots of lines which show it is a valid AD user. Some lines are
samAccountName:vikram
accountExpires:Never

So as you can see, its a valid AD user and the laptop is clearly connected to AD. So not sure why it doesnt recognize the user. Also su does not work
# su - vikram
No passwd entry for user 'vikram'
# su - vikram@simplead.xxx.xxx
No passwd entry for user 'vikram@simplead.xxx.xxx'
Please let me know what could be wrong.
Thanks,
Vikram
