Is an Active Directory delegation management tool. It allows you to make a detailed inventory of delegations set up so far in a forest, along with their potential issues:

• Objects owned by users
• Objects with ACEs for users
• Non canonical ACL
• Disabled ACL inheritance
• Default ACL modified in schema
• Deleted delegation trustees

It also allows you to document your delegation model in JSON files, to obtain a more readable view:

You can also use the tool from a terminal by passing any option to it (if you don't want to pass any particular option, just use --text):

If you want to export results, you can choose a CSV output using --csv my.csv This is also suitable if you are interested in differences introduced since a previous dump (e.g. in PowerShell, diff (cat export_new.csv) (cat export_old.csv) )

Results should be concise in forests without previous work in delegation management. If results are too verbose to be used, open an issue describing the type of results obscuring interesting ones, ideally with CSV exports or screenshots.

You can start using this inventory right away, in two ways:

1. look for highly privileged resources which have no reason to have any delegation set up on them, since they are only supposed to be managed by forest-wide administrators

2. you can also start the other way around, and look for trustees which have no reason to have any right delegated to them (e.g. day-to-day end user accounts)

How do I know if one result is important? Should I consider everything a problem? You should start reviewing delegations on your critical assets (domain controllers, domain admins, their admin workstations, servers with sensitive business data, etc.): are these delegations needed for a user or service to do their work? could they not work with fewer access rights, or on fewer objects?

My forest has years of delegations built up, how am I supposed to handle that many warnings? You may want to run the analysis periodically and only focus on differences, so that you can start from a baseline and clean up delegations little by little over time.

Can I import results from this tool into product ? Yes, if your tool knows how to parse CSV: .\adeleg.exe --csv dump.csv

This tool enumerates security descriptors of all objects, then filters out "expected" ACEs:

• Inherited ACEs, since we are only interested in the original ACE upper in the tree;
• ACEs in the defaultSecurityDescriptor of the object class in the schema;
• Some special cases which need to be handled manually.

Special cases currently include:

• object owners under a container with a CREATE_CHILD delegation
• ACEs for CREATOR_OWNER which are replaced and split in two in some cases during inheritance
• AdminSDHolder ACEs, for principals with adminCount set to 1
• KDS Root Keys, RODCs, ADCS, ADFS, Exchange, etc. are work in progress
