Is the hadith: "Its beginning is a mercy, its middle is forgiveness, and its end is emancipation from the Fire" authentic?

This is a fragment from the well-known hadith (definition) concerning Salman al-Farisi, which Ibn Khuzaymah transmitted in his Sahih (definition) and others. Ibn Khuzaymah prefaced it by saying, "If the report is authentic," which indicates his uncertainty about its authenticity. This hadith revolves around Ali ibn Zayd ibn Jud'an, who is weak, and scholars have discussed him. This hadith was declared weak by Al-Hafiz Ibn Hajar, Al-Ayni, and Shaykh Al-Albani, who described it as Munkar (denounced).
