It worked! Thanks so much for your help.

    Yes. Check existing ID ranges to see if you have one that covers POSIX ID
    755400050. If there is none, you need to create another ID range that
    covers those users.
    
    This typically comes from cases where POSIX IDs were assigned manually
    or from already existing source via migration. At this point FreeIPA
    would not have an ID range that covers these pre-allocated IDs.
    
    So you need to define several variables here:
    
     - base ID of the range
     - range size -- enough to cover those existing users and groups that
       are outside of IPA ID range
     - RID bases -- since we are building SIDs for the same domain, the RID
       base and secondary RID base should not be overlapping with existing
       IPA ID range
    
    For example, if you have 100 users starting around 755400000 and your
    default IPA ID range has 200000 entries (default range size), then
    mapping RID base above that one would be enough.
    
    ipa idrange-add MY.DOM.AIN-extra_id_range --base-id=755400000 --range-size=100 \
                                              --rid-base=500000 --secondary-rid-base=500100 \
    					  --type=ipa-local
    
    Adding this range would be enough -- there will not be any allocation of
    POSIX IDs in the range but sidgen plugin will be able to use the range
    to drive SID allocation.
