note 87607 added to function.sha1

My LDAP server performs a SSHA password hash that ends up looking like this MpvSdIo54QpREHaCH2rOg+83MPXsr9GF6kdk9A== That appears to be a 40 byte base64 encoded salted hash. I'm trying to recreate that and using... base64_encode(hash('sha1', $password)) I get a 56 byte base64 encoded hash. OTRlZjQwMmFiMzFiYzA4MjJiNWEzZjylYTUxYmIxODY0YWU3NWVkMw== Can someone help me figure out how the hash is derived and how I can recreate it via PHP? ---- Server IP: 64.71.164.2 Probable Submitter: 199.82.243.73 (proxied: 199.82.239.60) ---- Manual Page -- http://www.php.net/manual/en/function.sha1.php Edit -- https://master.php.net/note/edit/87607 Del: integrated -- https://master.php.net/note/delete/87607/integrated Del: useless -- https://master.php.net/note/delete/87607/useless Del: bad code -- https://master.php.net/note/delete/87607/bad+code Del: spam -- https://master.php.net/note/delete/87607/spam Del: non-english -- https://master.php.net/note/delete/87607/non-english Del: in docs -- https://master.php.net/note/delete/87607/in+docs Del: other reasons-- https://master.php.net/note/delete/87607 Reject -- https://master.php.net/note/reject/87607 Search -- https://master.php.net/manage/user-notes.php
