Hi @Kothai Ramanathan ,
Apologies for the delay in my response. After verifying with internal team, it is confirmed that, MSA/gMSA for On Premise connector may not support currently, given the condition that password is required/mandatory for On Prem file system connector.
I would recommend you to please share your feedback in ADF user voice forum and do share the feedback link here once it created. So that other users with similar idea can up-vote and/or comment on your feature request suggestion.
