What is the meaning of the name "Saden," and is it permissible to name males with it?

"The 'sadin' (سادن) is the servant of the Sacred Mosque (Masjid al-Haram). The term may also be applied to the servant of Jerusalem (Bayt al-Maqdis) or the servant of an idol. 'Sidanah' (سدانة) refers to the service of the Kaaba, taking charge of its affairs, and opening and closing its door. Shaybah ibn Uthman was the sadin of the Kaaba, and Abu al-Awwam was the sadin of Jerusalem. There is no religious prohibition against being called by this name."
