Username option while mounting Windows share without sudo /Ubuntu 22.04 server

If I try to mount Windows network share it uses actual Ubuntu user instead of given username.

mount -t cifs -o vers=3.0.2 -o username=Windows_username //share /mnt/smbPassword for Ubuntu_username@//share:

If I do it with sudo it correctly uses specified username option

sudo mount -t cifs -o vers=3.0.2 -o username=Windows_username //share /mnt/smbPassword for Windows_username@//share:

Before trying this I put line to /etc/fstab

//share /mnt/smb cifs noauto,user 0 0

Same result if I use credentials option with credentials file.

I want to mount share with Ubuntu user (use it in script), that doesn't have sudo privileges. I need to login to Windows share with Windows user, that has set privileges on that share.

Why regular Ubuntu user cannot use username option?
