[Samba] Schema change to support syncing distribution lists to O365

[Andrew Martin]

Hello,

Has anyone successfully added the "msExchRequireAuthToSendTo" attribute to Samba
AD? If so, how did you make this schema change? As documented below, this
attribute is used when syncing to Azure AD for O365 to control which
distribution lists can receive outside mail. I am familiar with how to make
schema changes, but could use some guidance on this specific one since it is
less well-documented and I know schema changes are irreversible.

Thanks,
