I take it you have "SymLinksifOwnerMatch" enabled on your userdirs.
Your users have /home/username as their homedir in the passwd file.
/home is a sybolic link to /usr/home, but "the owner doesent match"
It's as simple as that.
Change your users homedir to /usr/home/username using chsh or something, and you are set to go.
