This pull release introduces several important updates across the codebase, primarily focused on improving authentication mechanisms, enhancing the CMDB mode and host model, and refining Ansible inventory handling. The changes also include general code cleanup and documentation improvements.

Authentication and API Changes:

Replaced the x-login-header authentication header with x-login-user, updating all relevant API endpoints, documentation, and security definitions for consistency and clarity. The authentication logic now uses the User model and checks the password with check_password.

CMDB Mode and Host Model Enhancements:

Added support for CMDB mode in configuration (CMDB_MODE and CMDB_MODELS), and extended the Host model with new fields (cmdb_fields, cmdb_template, last_import_id). Introduced the CmdbField embedded document for flexible field storage. [[1]](https://github.com/kuhn-ruess/cmdbsyncer/pull/71/files#diff-556ffb367cabead355f9000bec3b8d09405a54e33e3349892ecb6a777db90825R113-R114) [[2]](https://github.com/kuhn-ruess/cmdbsyncer/pull/71/files#diff-556ffb367cabead355f9000bec3b8d09405a54e33e3349892ecb6a777db90825R123-R138) [[3]](https://github.com/kuhn-ruess/cmdbsyncer/pull/71/files#diff-16c58a535854a27f7cc607a43cb9b08b8a805a427981a094ecaa1cf0889adfafL23-R31) [[4]](https://github.com/kuhn-ruess/cmdbsyncer/pull/71/files#diff-16c58a535854a27f7cc607a43cb9b08b8a805a427981a094ecaa1cf0889adfafL40-R46) [[5]](https://github.com/kuhn-ruess/cmdbsyncer/pull/71/files#diff-16c58a535854a27f7cc607a43cb9b08b8a805a427981a094ecaa1cf0889adfafL53-R64)
Improved host import and cleanup logic with the new delete_host_not_found_on_import static method and additional inventory attribute handling. Updated set_account to respect CMDB mode and use the new import ID. [[1]](https://github.com/kuhn-ruess/cmdbsyncer/pull/71/files#diff-16c58a535854a27f7cc607a43cb9b08b8a805a427981a094ecaa1cf0889adfafR88-R116) [[2]](https://github.com/kuhn-ruess/cmdbsyncer/pull/71/files#diff-16c58a535854a27f7cc607a43cb9b08b8a805a427981a094ecaa1cf0889adfafL342-R397) [[3]](https://github.com/kuhn-ruess/cmdbsyncer/pull/71/files#diff-16c58a535854a27f7cc607a43cb9b08b8a805a427981a094ecaa1cf0889adfafR411-R413) [[4]](https://github.com/kuhn-ruess/cmdbsyncer/pull/71/files#diff-16c58a535854a27f7cc607a43cb9b08b8a805a427981a094ecaa1cf0889adfafR436-L381)

Account Model and Types Improvements:

Expanded the list of supported account types and added a template type for CMDB labels. Refactored the Account model to use type instead of typ, providing backward compatibility via a property. [[1]](https://github.com/kuhn-ruess/cmdbsyncer/pull/71/files#diff-ca5b141626287331063637b809556852358a35b296a3286f66cd475cf0ac8ba5R11-R33) [[2]](https://github.com/kuhn-ruess/cmdbsyncer/pull/71/files#diff-ca5b141626287331063637b809556852358a35b296a3286f66cd475cf0ac8ba5R55) [[3]](https://github.com/kuhn-ruess/cmdbsyncer/pull/71/files#diff-ca5b141626287331063637b809556852358a35b296a3286f66cd475cf0ac8ba5L72-R117)

Ansible Inventory and Playbook Updates:

Updated Ansible inventory scripts: replaced the old inventory script with a documentation note, and added a new inventory_single script for faster host-specific inventory generation. Fixed a typo in the cleanup playbook to enable tasks. [[1]](https://github.com/kuhn-ruess/cmdbsyncer/pull/71/files#diff-6ef150b198b9cf49c007d9e098710ed083fac123177df92c443fefd84ad32560L1-R1) [[2]](https://github.com/kuhn-ruess/cmdbsyncer/pull/71/files#diff-cee9ed78e4992a6f026428583fcf02ff7b486e20d2e195bf435d5117097d72a2R1-R28) [[3]](https://github.com/kuhn-ruess/cmdbsyncer/pull/71/files#diff-f4f017cf8b44d51741a832a6d6b482586ceea9e710f2036817fad842b884c0f2L7-R7)

General Codebase Cleanup and Documentation:

Improved documentation and code comments in models and configuration files. Removed unused imports and updated versioning in application/__init__.py. [[1]](https://github.com/kuhn-ruess/cmdbsyncer/pull/71/files#diff-1b4edbe81db1496f2c1e16e23959787445b422d14cfd34bb07682643cc1ce459L10-L13) [[2]](https://github.com/kuhn-ruess/cmdbsyncer/pull/71/files#diff-1b4edbe81db1496f2c1e16e23959787445b422d14cfd34bb07682643cc1ce459L23-L34) [[3]](https://github.com/kuhn-ruess/cmdbsyncer/pull/71/files#diff-de7ec3042dd5439c0ee22413010ab35deae91ab8e1e95d0503bd59d82c98ed75L8-R8) [[4]](https://github.com/kuhn-ruess/cmdbsyncer/pull/71/files#diff-de7ec3042dd5439c0ee22413010ab35deae91ab8e1e95d0503bd59d82c98ed75L59-R59) [[5]](https://github.com/kuhn-ruess/cmdbsyncer/pull/71/files#diff-ade8f5ff16323b428edb6463ffb52d56822294039615645ed370b51dce380cc0L12)

These changes collectively improve security, maintainability, and flexibility for both API consumers and internal data management.

The New Version's main visible improvements are in the User Interface.
New Styling Options are now introduced, with which help the Forms for example for Conditions are now more user-friendly.

As a result of Pentesting, the Syncer now Saves Account Passwords Encrypted. It's nothing to do for you, then run ./cmdbsyncer sys self_configure after update (which you should do anyway).
Also, you need to update the requirements (if not using docker) otherwise you will get exceptions on start because of missing modules.

Account Updates

Accounts a basic Config Containers. Now you can create child instances of them.
The Child's will inherit the Credentials and other settings, but you can overwrite there stuff if needed.

This is useful, for example, if you want to use multiple DB Filters for Objects when exporting Checkmk Rules.

For Docker Users:

Cronjobs are now integrated into the Container. No need anymore to call something from outside.
Also: the self_configure functions will happen automatically, no manual step needed.

Additionally, this Versions Supports imports from JDISC.

Furthermore, the GUI is improved, looks more modern with Syntax Highlighting for Jinja codes.
The Syncer also Stores now the original data types on imports, so it's simpler to use Jinja Functions.

The Logging is now completed in the GUI, and you can use Checkmk Checks to monitor your Syncer jobs.

Debugging is also improved, many commands now support --debug to show the debug mode if needed, which no longer needs to be enabled in the config. With --debug-rules DEVICENAME many modues now support a Rule Debug view.

The Export to Checkmk is also faster then before, and the Checkmk Export functions now automatically detect the Target Checkmk Version and adjust the API Calls if needed.

• Export of Hosts and Tags to Checkmk, use now all available Processing Power to calculate Rules before importing.
• Bulk Operations for Checkmk are now Enable as Default
• Speed speed speed for Checkmk Operations

Supported Versions

• Checkmk: API Calls are Adapted to Checkmk 2.3 and some functions may not work on 2.2
  - Checkmk Rules: On 2.2 the rules will delete and created again all the time due an API change in Checkmk.
• SET local_config: 'CMK_SUPPORT': '2.2' to make version better compatible to old 2.2

Interaction Needed

• CSV: On Import, Hostnames are only set to lowercase if set in local_config.py. No longer as Default. See Local Config
• MySQL: On Import, Hostnames are only set to lowercase if set in local_config.py. No longer as Default. See Local Config

• General: Jina Placeholder for Hostsname is now always Uppercase HOSTNAME.
• Checkmk: The Checkmk API once allowed, accidentally, that a host could be converted to a cluster. Since that is no longer possible, the Syncer now deletes hosts which should become a cluster to recre
  ate them as such.
• General: Config introduced "CRYPTOGRAPHY_KEY". Please overwrite it, since it is used to encrypt stored passwords in the database
• CRON: The Maintenance Cronjob had a Typo. After Update, you need to reelect this command in the config of the cron group.

• Checkmk: Support to manage Password Store
• Checkmk: Detailed logging (if enabled) for changes made
• Global: Changes on Import hosts for Labels are now logged inside the Host Objects log
• LDAP: Added Support for Inventorize

This Version is the last Version before the Multiprocessing Features.

This Version does only contain some minor new features and improvements.
But it has two incompatible Changes.

1. New Python Modules used as result of Security Updates.
2. Inventory Data has now a new prefix Style.

One can be resolved without much effort for the most of the users. But the second one
may need an update of your rules since the attribute naming for inventorized data is effected.
Not effected are rules which are based on attributes which are imported by normal plugins.

So please refer to the Documentation for this update:
https://cmdbsyncer.readthedocs.io/en/latest/updates/3-5/
