Subject: ITS#8360 fix ad info after failed txn
X-Git-Url: https://git.sur5r.net/?a=commitdiff_plain;h=4001eb054f234543be845d50a49cfe8787f8f0a3;p=openldap

ITS#8360 fix ad info after failed txn

If an add or modify op referenced a previously unused attrtype,
the mi_ads/mi_numads would be incremented to include it. If the
op fails to commit, these additions must also be reverted.
