Hello @obe_samuel ,
Taiga does not have a system to integrate with AD in the core of the application, but the community has developed plugins for LDAP integration that might work for you.
In this thread you can read about it Integrate an LDAP account database with Taiga
There is another plugin, although it seems that it has been inactive for a long time. GitHub - stemid/taiga-contrib-ad-auth: Taiga AD Authentication plugin
I hope this can help.
Best regards
