First of all, then if you think that just because none of us has so far understood 1: the context (you have not filled in the support template. You have not added anything remotely usefull to understand how and what you do other than vague hints.) is not really context and thus we have nothing to go with. 2: Your post are not structured in a way that a descriptive format apparently has made any sense to us - that it certifies you to be that disrespectfull, it is all on you. I am out of this thread.
To be clear - and with that answer you sent me I should not be helping you anymore - then everytime you do ADMINISTRATIVE tasks, Nextcloud WILL ask for your password. This is for security reasons, and usually you would use the build in Admin user - which is NOT in your LDAP hence is a local-only user with a local password. In a federation scenario especially, you will need to have a local password (an app password can be used…!) if you are using a federated user as administrator. This is unavoidable.
