If I understand you ok, you used an exported ldif file from netscape to setup all your existing mail accounts to qmail/vpopmail, right? -- absolutely
Using ldap as auth engine on vpopmail's ldap module, or local userdb files? -- no, just mysql as storage You imported your cyphered SHA-1 strings from netscape database, ok. Then, once inserted in vpopmail users database, vchkpw and authdaemon recognize such SHA-1 strings to validate users' passwords? -- yes, some vpopmail code was modified to support this format. so you can have sha-1 passwords & md-5 passwords at the same time.
