i've read somewhere (can't recall) that nirodha samapatti(ninth jhana) can be experienced with access concentration and that the jhanas are not entirely necessary for this to occur.

Well, nirodha samapatti is a very deep level of absorption. I cannot fathom how a mind attends to it without first going through the jhanas.

Imo, you are possibly misinterpreting the commentaries here. Some commentaries say that any realization which happens to a meditator in this state, does happen when the mind arises from it (access concentration) rather than when absorbed in it. This conclusion is only logical since nirodha samapatti is cessation of perception and feeling. However, this conclusion is again not explicit in the suttas but in the commentaries. You seem to be interpreting this as "jhana is not required for nirodha samapati."

i believe the first time one experiences nirodha samapatti it may be sudden and last but a few mind moments, i read that this is called GLIMPSING nibbana and when the mind starts again and the senses come back on-line this person is sotapanna(the lowest degree of saints) 3 fetters have been extinguished identity view, doubt, clinging to rites and rituals.

Again in commentaries, it is mentioned that a person arising from this state is either anagami or arahath. Is what you describe here supported in suttas? For sothapanna state, it doesn't seem like jhana is even needed.

Either way, the suttas do NOT give any special importance to nirodha samapatti in terms of complete cessation because it is not talked about as something essential but rather as additional. The Buddha has said it is possible to attain nibbana with the first 4 jhanas.
