The format is based on Keep a Changelog, and this project adheres to Semantic Versioning.

[Unreleased]

[v7.0.8-6] - 2024-11-25

Fixed

  • Prevent logging of invalid login credentials [#233]

Added

  • Integration test searching for unencrypted passwords in the cas logs [#225]

[v7.0.8-5] - 2024-11-21

Breaking Change

  • Newly installed dogus must explicitly request the creation of a service account in the CAS via dogu.json. Further information on this can be found in the developer documentation

Changed

  • Use JSON service registry [#221]
    • services are read from and stored in json files instead of local config
    • native implementation from CAS is used for this, which reduces custom overlay implementation
  • Changed logic to create and remove service accounts [#221]

Removed

  • Reading service information directly from ETCD [#221]
    • Removed java classes for service creation

Fixed

  • Fix ServiceIdFQDN regex by changing illegal url characters [#228]

[v7.0.8-4] - 2024-11-13

Added

  • Replicate users from delegated authentication into LDAP [#224]
    • delegated authentication currently only works when using the embedded LDAP
  • Disclaimer for legal_urls without protocol [#230]

Fixed

  • Fix configuration for delegated authentication with OIDC [#222]

[v7.0.8-3] - 2024-10-11

Changed

  • Use flat instead of nested attributes for OAuth user profile. [#219]

Fixed

  • OIDC- and OAuth-Dogus which relied on a flat OAuth user profile structure were unable to parse the user profile. [#219]

[v7.0.8-2] - 2024-10-02

Fixed

  • Fix a bug where the watch for service accounts in the config local.yaml stucks because the events wasn't resetted and polled [#217]

[v7.0.8-1] - 2024-09-23

Added

  • Add "lang"-attribute to HTML-Pages [#213]
  • update CAS to 7.0.8

[v7.0.5.1-8] - 2024-09-18

Changed

  • Relicense to AGPL-3.0-only

[v7.0.5.1-7] - 2024-09-05

Fixed

  • The pre-upgrade-script will no longer try to access the node_master-file for all migrations [#211]
    • The access to the node_master-file has been moved to the migration where it es needed and where the node_master-file was still present.

[v7.0.5.1-6] - 2024-08-27

Fixed

  • The post-upgrade-script would fail in a specific edge-case situation [#207]
    • Affected System: Cloudogu EcoSystem 'Classic' (Pre-Multinode)
    • Affected versions: 7.0.5.1-4 and 7.0.5.1-5
    • When an OAuth/OIDC-Dogu was installed and then uninstalled, the post-upgrade script would fail during an upgrade from CAS versions below 7.0.5.1-4.
    • This means that a directory /config/cas/service_accounts/<type> had to exist, but be empty (where <type> can be oauth or oidc).
    • Additionally prevent similar cases.

[v7.0.5.1-5] - 2024-08-20

Fixed

  • Add missing data-testid to logout error messages [#203]
  • Add missing translations

[v7.0.5.1-4] - 2024-08-20

Changed

  • In a single-node EcoSystem (Classic-CES):
    • Use explicit service accounts for normal CAS service accounts in addition to implicitly reading dependencies. (#197)
    • Receive logout URI as an additional argument in the service-account-create exposed command in addition to reading it from the dogu descriptor. (#197)
  • In a multi-node EcoSystem:
    • Use explicit service accounts for normal CAS service accounts instead of implicitly reading dependencies. (#197)
    • Receive logout URI as an additional argument in the service-account-create exposed command instead of reading it from the dogu descriptor. (#197)
  • Use config from mounted file when in multinode (#197)
  • Upgrade java base image to 21.0.4-1 (#193)
  • Replace persistent state with local config (#193)

[v7.0.5.1-3] - 2024-08-16

Fixed

  • Fix design of login mask to be more flexible

[v7.0.5.1-2] - 2024-08-15

Changed

  • Modify the whole cas ui to match with our new theme (#201)

[v7.0.5.1-1] - 2024-07-23

Fixed

  • Fix throttling and avoid rendering CES unusable (#198)
    • when intensely sending REST requests towards Nexus with an internal user

Changed

  • migrate dogu configuration keys regarding throttling (#198)
    • with CAS 7.x, throttling works way differently than before, and with different configuration keys as well
    • limit/max_numbers no longer enables throttling in general
      • now, limit/failure_threshold with a value other than zero takes it place. With a default value of 500 login failures / timeframe, it will receive a much higher default value though.
    • limit/range_seconds is a new configuration key. It defines the timeframe in seconds and is used to build a failure rate with limit/failure_threshold.
    • limit/stale_removal_interval is a new key which configures now the interval in seconds of when a background runner runs to remove stale login failures. The interval is independent of limit/failure_threshold
  • update CAS to 7.0.5.1
  • update Tomcat to 10.1.26

Removed

  • remove the custom throttling implementation in favor of the original CAS 7 failure throttling implementation (#198)

Security

[v7.0.4.1-2] - 2024-07-09

Fixed

  • Fix a bug where CAS logs the password in debug log level (#195)

[v7.0.4.1-1] - 2024-06-06

Changed

  • Upgrade CAS to 7.0.4.1 (#189)
    • CAS 7.0 contains a "weak password detection" that checks on every login if the password complies with the configured password-rules. If a password does not comply a warning is displayed and the user has to enter a new password that complies with the rules.

[v6.6.15.1-1] - 2024-05-24

[v6.5.8-2] - 2023-03-22

Fixed

  • Fix file system exhaustion from Tomcat access logs in /opt/apache-tomcat/logs (#173)
    • The access logs will be streamed to Stdout instead, t. i., the logs will be accommodated by the hosts /var/lib/docker/cas.log

[v6.5.8-1] - 2022-11-17

  • Upgrade cas to 6.5.8 (#171)

[v6.5.5-4] - 2022-08-23

Changed

  • Set the ldap-min-pool-size to zero also for the password management ldap (#136, #169)

[v6.5.5-3] - 2022-08-17

Added

  • Make password policy configurable. For more information see docs (#167)

[v6.5.5-2] - 2022-07-07

Changed

  • When resetting the password, certain e-mail addresses are declared invalid in the original CAS code, e.g. [email protected]. This has now been adjusted. E-mails are now sent to all e-mail addresses (concretely: forwarded to Postfix). (#163)

[v6.5.5-1] - 2022-06-30

Changed

  • Update cas to v6.5.5 (#164)

[v6.5.5-1] - 2022-06-30

Changed

  • Update cas to v6.5.5 (#164)

[v6.5.3-8] - 2022-05-25

Changed

  • Suppress determination of an existing username via password reset function (#161)
    • Previously, an error message has been displayed if a username does not exist in the system. If the username is present in the system, a confirmation that an email has been sent followed. Now a confirmation page with customised text is displayed in both cases.

[v6.5.3-7] - 2022-05-18

Fixed

  • If CAS version 6.3.7-5, 6.5.2-1 or 6.5.3-1 has been used and an upgrade to a version >= 6.5.3.2 has been carried out, the migration of the service account for the LDAP from the read account to the write account is not performed. This resulted in a password change not being saved by the user and the user receiving an error message. This error has now been corrected. (#159)

[v6.5.3-6] - 2022-05-11

Added

  • Password Reset Functionality. For more information see docs (#156)

Fixed

[v6.3.7-2] - 2022-01-11

Fixed

  • Remove dogu configuration key ldap/use_user_connection_to_fetch_attributes. From now on, all connections to the LDAP to fetch user attributes are made via the system connection. (#103)

A new CES registry key logging/root is evaluated to override the default root log level (#49). One of these values can be set in order to increase the log verbosity: ERROR, WARN, INFO, DEBUG.

CAS's Log4J log levels are directly applied from the root log level.

Tomcat log levels are mapped from the root log level as follows:

root log level Tomcat log level
ERROR Everything equal or above ERROR
WARN Everything equal or above WARNING
INFO Everything equal or above INFO
DEBUG Everything equal or above FINE

Changed

  • Under the hood we verify the Tomcat binary to spot (possibly) tampered Tomcat binaries during the build time. (#38)

Fixed

  • PerformanceStats are no longer logged to the container filesystem for reasons of discoverability and performance. Instead they are logged to the usual CES logging facility. (#48)
