It is on purpose, yes. There should be a related issue and PR in this repo, too.

I read some supposed performance limitations on big LDAP organisations. But:
- all i read on LDAP documentation never mention "don't do term" as it is even described in the main documentation.
- this might be based on old benchmarks on bad LDAP system
- why is the "*" allowed that will send "all users" in that case ?
- the SQL part does the term and nobody asked to remove this for performance reason
- this is very very confusing for the user experience (i thought this was a bug and i lost hours searching what was wrong with my LDAP until i debug in PHP)
In conclusion, at least, why presuming all ldap are made with millions of users ? Why not let users have the same behaviour between LDAP and NextCloud ? And maybe bring an LDAP option "don't allow term because my ldap is too slow" if someone complain for it ?

If you make it a config option, maybe, but we cannot merge this as-is.
I do not have the details about when the decision was first taken, and I agree that with a good LDAP setup wildcard search is not an issue, but there is a lot of code in Nextcloud which is made to account for badly configured LDAP server, this is not the only place.

This issues were close, but because the user "didn't use NextCloud anymore"
Summary
In Database User Backend, search is based on "term". But in LDAP, it's only "term*". This is confusing for user experience.
