If you are using LDAP naming services, creating automount path names which are the same except for case will result in non-unique path names. The directory server does not allow creation of entries where the naming attribute is defined with a case-sensitive syntax and an entry already exists with the same name, but different case. For example, if entry attr=foo,dc=mycompany,dc=com exists, the server will not allow creation of attr=Foo,dc=mycompany,dc=com. A side effect of this problem is when LDAP naming services are used, automount path names have to be unique regardless of their case.
It is not possible to have /home/foo and /home/Foo paths.
