Alright, I have created a file contrib/slapd-modules/passwd/apr1.c which implements this hash: http://openldap.pastebin.com/r2GzfveB I have tested it and confirmed that it works on several passwords converted from an htpasswd file using the atol.pl script above.

New password hash mechanisms should simply be implemented as standalone modules for inclusion under contrib/slapd-modules. See contrib/slapd-modules/passwd for existing examples. -- -- Howard Chu CTO, Symas Corp. http://www.symas.com Director, Highland Sun http://highlandsun.com/hyc/ Chief Architect, OpenLDAP http://www.openldap.org/project/

(ITS#6826) Apache htpasswd MD5 support [patch]
by djpohly＠gmail.com 04 Feb '11

Full_Name: Devin J. Pohly Version: 2.4.23 OS: Linux URL: http://openldap.pastebin.com/t4jWaUfe Submission from: (NULL) (75.102.64.250) == Proposed enhancement == When migrating an Apache .htpasswd-based system to LDAP authentication, it would be nice if the password hashes would migrate cleanly. .htpasswd uses three hash formats: {SHA}, {CRYPT}, and "apr1", an MD5-based variant not supported by OpenLDAP. If OpenLDAP had a hash which was equivalent to (i.e. could be freely converted to and from) Apache's apr1, conversion would be easy. == Solution == If you're willing to have OpenLDAP depend on APR-Util, it would be trivial to use the apr_md5_encode and apr_password_validate functions to support this hash. If not, I created a patch [1] which implements the apr1 hash. The algorithm is the same as PHK MD5 with a different magic number. I derived the code from the PHK source which is freely usable under the Beer-ware license (see patch). This patch adds an {APR1} hash type to OpenLDAP when configured with --enable-apr1. [1] http://openldap.pastebin.com/t4jWaUfe (Note: patch is against release, but passwd.c has not changed significantly in HEAD.) == Discussion == The patch has held up to my (limited) testing, but it could probably be written better. It might be useful to put the algorithm into its own function or file, since it's fairly complex and used in both the chk_apr1 and hash_apr1 functions. It might also be useful to specify the magic number to the functions; then we would get PHK $1$ hashes for free. Apache selects salts with 48 bits of randomness but treats them as 64-bit salts. The lines referring to apr64[] replicate this behavior for backward compatibility (so {APR1} hashes generated by slappasswd can be converted to .htpasswd). If you're not concerned about being able to convert in the opposite direction, that code can be removed, and OpenLDAP can then use any size salt. == Tools == The hashes are stored in OpenLDAP's base64(hash + salt) format for consistency. I put together a couple pipe-able scripts for converting between Apache's $apr1$ and OpenLDAP {APR1} formats: Apache to OpenLDAP: http://openldap.pastebin.com/0SSbzjhH OpenLDAP to Apache: http://openldap.pastebin.com/rfLBRASr

The workaround works, thanks for the quick response! There will be other uniqueness scenarios where it will be good to have the full functionality, but for this situation we should be fine.
