Hello list
I have a similar problem with 3.0.24

after upgrading configuration all rids in database looks like mismatched
with the new mapping

and I wasn't able to clear the DB nor to reset rids mapping

Yet I have no error and no panic from samba or winbind.

        security = ADS
        passdb backend = tdbsam
        passwd program = /usr/bin/passwd %u
        preferred master = No
        winbind enum users = Yes
        winbind enum groups = Yes
        winbind use default domain = Yes
        winbind nss info = rfc2307
        idmap backend = idmap_rid:DMSWARE=500-100000000
        idmap uid = 10000-50000
        idmap gid = 10000-50000
