Authentication Service and Privilege Elevation Service 6.0.0 Release Notes (Server Suite 2023)

About this Release

Authentication Service and Privilege Elevation Service, part of the product category Delinea Server Suite (previously called Centrify Infrastructure Services or Centrify Zero Trust Privilege Services), centralize authentication and privileged user access across disparate systems and applications by extending Active Directory-based authentication, enabling use of Windows Group Policy and Single-Sign-On. With Delinea Server Suite, enterprises can easily migrate and manage complex UNIX, Linux, and Windows systems, rapidly consolidate identities into the directory, organize granular access and simplify administration. Delinea Authentication Service, through Delinea's patented Zone technology, allows organizations to easily establish global UNIX identities, centrally manage exceptions on legacy systems, separate identity from access management and delegate administration. Delinea's non-intrusive and organized approach to identity and access management results in stronger security, improved compliance and reduced operational costs.

The Upgrade Guide describes the correct order to perform updates such that all packages continue to perform correctly once upgraded.

Known Issues

The following sections describe common limitations or known issues associated with this Authentication Service and Privilege Elevation Service release.

For the most up to date list of known issues, please login to the Customer Support Portal at https://www.delinea.com/support and refer to Knowledge Base articles for any known issues with the release.

Server Suite DirectControl Agent for *NIX

• Known Issues with Multi-Factor Authentication (MFA)

  If MFA is enabled but the parameter "adclient.legacyzone.mfa.required.groups" is set to a non-existent group, all AD users will be required for MFA. The workaround is to remove any non-existent groups from the parameter. (Ref: CS-39591b)

• Known Issues with AIX

  On AIX, upgrading DirectControl agent from 5.0.2 or older versions in disconnected mode may cause unexpected behavior. The centrifydc service may be down after upgrade. It's recommended not to upgrade DirectControl agent in disconnected mode. (Ref: CS-30494a)

  Some versions of AIX cannot handle username longer than eight characters. As a preventive measure, we have added a new test case in the adcheck command to check if the parameterLOGIN_NAME_MAX is set to 9. If yes, adcheck will show a warning so that users can be aware of it. (Ref: CS-30789a)

• Known issues with Fedora 19 and above (Ref: CS-31549a, CS-31730a)

  There are several potential issues on Fedora 19 and above:

  1. The adcheck command will fail if the machine does not have Perl installed.
  2. Group Policy will not be fully functional unless Text/ParseWords.pm is installed.

• Known issues with RedHat

  When logging into a RedHat system using an Active Directory user that has the same name as a local user, the system will not warn the user of the conflict, which will result inunpredictable login behavior. The workaround is to remove the conflict or login with a different AD user. (Ref: CS-28940a, CS-28941a)

  • Known issues with rsh / rlogin (Ref: IN-90001)
  • When using rsh or rlogin to access a computer that has DirectControl agent installed, and

    where the user is required to change their password, users are prompted to change their

    password twice. Users may use the same password each time they are prompted, and the

    password is successfully changed.

• Known issues with compatibility

  Using DirectControl 4.x agents with Access Manager 5.x (Ref: IN-90001)

  • DirectControl 4.x agents can join classic zones created by Access Manager 5.x. It will

    ostensibly be able to join a DirectControl 4.x agent to a hierarchical zone as well,

    but this causes failure later as such behavior is undefined.

  Default zone not used in DirectControl 5.x (Ref: IN-90001)

  • In DirectControl 4.x, and earlier, there was a concept of the default zone. When Access Manager

    was installed, a special zone could be created as the default zone. If no zone was specified

    when joining a domain with adjoin, the default zone would be used.
  • This concept has been removed from DirectControl 5.0.0 and later as it is no longer relevant with hierarchical zones. In zoned mode, a zone must now always be specified.
  • A zone called "default" may be created, and default zones created in earlier versions of Access Manager may be used, but the name must be explicitly used.

Smart Card

• Release 18.8 includes an update to Coolkey to support Giesecke & Devrient 144k, Gemalto DLGX4-A 144, and HID Crescendo 144K FIPS cards. However, this has caused known issues that may cause CAC cardsto only work sporadically. A workaround for CAC cards is to wait for it to prompt for PIN and Welcome, without removing the card, and then try again. (Ref: CC-58013a)

• There is a Red Hat Linux desktop selection issue found in RHEL 7 with smart card login. When login with smart card, if both GNOME and KDE desktops are installed, user can only log into GNOME desktop even though "KDE Plasma Workspace" option is selected. (Ref: CS-35125a)

• When a SmartCard user attempts to login with a password that has expired, the authentication error message may not mention that authentication has failed due to an expired password. (Ref: CS-28305a)

• Any SmartCard user will get a PIN prompt even if he's not zoned, even though the login attempt will ultimately fail. (Ref: CS-33175c)

• If a SmartCard user's Active Directory password expires while in disconnected mode, the user may still be able to log into their machine using their expired password. This is not a usualcase, as secure SmartCard AD environments usually do not allow both PIN and Password logins while using a Smart Card. (Ref: CS-28926a)

• To login successfully in disconnected mode (Ref: CS-29111a):

  • For a password user:

    * A password user must log in successfully once in connected mode prior to logging in

    using disconnected mode. (This is consistent with other DirectControl agent for *NIX behavior)

    • For a SmartCard user:
      • The above is not true of SmartCard login. Given a properly configured RedHat system with

        valid certificate trust chain and CRL set up, a SmartCard user may successfully login

        using disconnected mode even without prior successful logins in connected mode.

        • If certificate trust chain is not configured properly on the RedHat system, the SmartCard user's login attempt will fail.
        • If the SmartCard user's login certificate has been revoked, and the RedHat system has a valid CRL that includes this certificate, then the system will reject the user.

• When CRL check is set via Group Policy and attempting to authenticate via Smartcard, authentication may fail. The workaround is to wait until the Group Policy Update interval has occurred andtry again or to force an immediate Group Policy update by running the CLI command adgpupdate. (Ref: CS-30090c)

• A name-mapping user can unlock screen with password even though the previous login was with PIN. (Ref: CS-31364b)

• Need to input PIN twice to login using CAC card with PIN on RedHat. It will fail on the first input but succeed on the second one. (Ref: CS-30551c)

• Running "sctool -D" with normal user will provide wrong CRL check result. The work-around is to run it as root. (Ref: CS-31357b)

• Screen saver shows password not PIN prompt (Ref: CS-31559a)

Most smart card users can log on with a smart card and PIN only and cannot authenticate with a username and password. However, it is possible to configure users for both smart card/PIN and username/password authentication. Generally, this set up works seamlessly: the user either enters a username and password at the log on prompt, or inserts a smart card and enters a PIN at the prompt.

However, for multi-user cards, it can be problematic when the screen locks and the card is in the reader. When a user attempts to unlock the screen, the system prompts for a password, not for a PIN, although the PIN is required because the card is in the reader. If the user is not aware that the card is still in the reader and enters his password multiple times, the card will lock once the limit for incorrect entries is reached.

On RHEL 7, an authenticated Active Directory user via smart card cannot login again if the smart card is removed. This is due to a bug in RHEL 7, https://bugzilla.redhat.com/show_bug.cgi?id=1238342. This problem does not happen on RHEL6. (Ref: CSSSUP-6914c)
