Hi.
The plugin allows you to have LDAP/AD based accounts as well as WordPress installation based accounts in parallel.
Internally it checks whether it can authenticate a user based on the configuration against LDAP/AD and if that does not works, then the authentication process is delegated to the next authentication method which then falls back in the end to authenticating against the WordPress installation.
YOu can also set up the plugin in a way that the authentication is handled against LDAP/AD and the authorization (group memberships and therefore access rights) are handled via the WordPress roles.
Each user that authenticates via LDAP/AD is created in the WordPress installation and can then be managed within WordPress regarding access rights.
Regarding the account profiling though I’m not sure I 100% understand what you want to do. The plugin allows to add users to different WordPress groups based on the LDAP/AD groups they are member of. If you can create different sections for different users via groups in WordPress then the plugin should allow you to populate those WordPress groups with users based on information you find in the LDAP/AD.
Hope that helps and answers all questions. If not, please get back.
Regards
Andreas
