[TYPO3-dam] DAM cannot upload file in fileadmin

[Aleksandar Milovac]

I just installed fresh 4.3 T3 with dam 1.1.1. When I try to upload file
to fileadmin/ I get error message: You are not allowed to upload file!
When I use classic File module upload is possible.

Is this a bug or...? Any clues?

Thanks,
Aleksandar
