migrating from (old) /etc/shadow to LDAP

Hi all. Im migrating the /etc/shadow accounts to an LDAP enviroment.

As the /etc/shadow containing server has suffered several upgrades, there is more than one crypto mechanism applied.

Some entries are in the form $2a$10$..... this is an {CRYPT} entry, and have no problems with that.

Others (the oldest ones) doesn't seem to have a prefix at all. There are "short" strings like bHwTgdCTnfpco lJvWLr8sfW.Hg and so on...

I tried with {MD5}, {SHA} + encrypted password with no luck.

Any one knows which crypto mechanism is applied here? I think they are from an old Suse 9.1 (not the Enterprise Server Edition, the realy old SuSE 9.1)

Thanks!
