Why not just tell us how you store accounts with samples, so that we can work together to migrate them?

- Password in /etc/shadow can be migrated into LDAP.
- Password genereated via MYSQL encrypt() works in LDAP:

mysql> SELECT ENCRYPT('test');
+-----------------+
| ENCRYPT('test') |
+-----------------+
| ihcgGah8lhxqk   | 
+-----------------+

How do you generate other passwords? MD5, SHA1/shadow, you mentioned above.

We have so many system, this would be systems from the old owner and every of the use his own.

We have 1800 customers with Encrypt, 200 with MD5, 300 with old shadow passwords copy from linux in a MySQL DB, 5000 with cyrus in sasldb2, 3600 in a IMail Ipswitch System, 2300 in a old Ensim, 7100 with linux shadow/password.

I have copy the passwords from the systems that run at the moment, but i have only from 2% of the users, the passwords in plaintext.

May i know how did you generate these passwords?

No problem, we wil ony use OpenLDAP, but we musst migrate all other servers to this system and the next step is setup a cluster with fallback.

MySQL SET `password` = ENCRYPT( 'test1' )

Sorry:

- Not sure cyrus can be migrated.
OK, but we can try it...
- Which encrypt mech do you use in MySQL? MD5?
MySQL encrypt and MySQL md5
- Shadow MD5? do you mean /etc/passwd? It's OK to migrate to LDAP, but not sure to MYSQL.

Shadow MD5 like "$1$mtxL9Xwv$jGBIg9yoSoEpC.bJbWCU30"

Thanks
