OK… So, I have posted on the Centos list, comp.security.ssh, and Linux Forums,
and no one seems to have heard of this issue or even have any advice for me.
So, I am going to take a shot with the Samba list, since this is related.
I have a Centos 6.2 server freshly updated. It is authenticating against an
openldap server, and I am having an issue with the hashing algorithms being
used by various utilities and servers.
First of all:
authconfig --test | grep hashing
password hashing algorithm is sha512
However, when I change a password using the passwd command, I see the following:
smbldap-usershow al...@domain.com
dn: uid=al...@domain.com,ou=domain,o=ndtc
uid: al...@domain.com
cn: Alex M
mail: al...@domain.com
...
userPassword: {crypt}$1$kxH/MHL7$.51e8u0CooCalDaXsHSKD/
Crypt? OK, well, it's a crypt (MD5) password even though authconfig says it'll
be using sha512... But, I can log in using sshd.
Now, if I change the password using the smbpasswd utility (I'm using "ldap
password sync = yes"), and rerun the smbldap-usershow command:
dn: uid=al...@domain.com,ou=domain,o=ndtc
uid: al...@domain.com
cn: Alex
mail: al...@domain.com
...
userPassword: {SSHA}UGRSbhcFL0qLRdj6yWvqRidZPfIiBPYb
OK, now it's an SSHA hash! Hooray! BUT, I can no longer ssh to the server!
WTF??? Anyone have any insights into what I am missing here, and more
importantly, how I can fix it? I'd obviously rather use SSHA than MD5...
TIA!
Alex
