Hi there!
I have recently migrated my old server from OpenSUSE 10.0 to CentOS 5. Almost everything works great, except for one thing - user passwords. In the old system they were in a form:
root:$2a$05$9V.P3/KV2fd0r/O8hs0gNueaidF35edj3DL6skb32qZJNpvwVHiUO:12183:0:99999:7:::
and that format doesn't seem to be understood by CentOS. When I change the password I get something like:
root:$1$Z0HGYkIb$fbkW0gR6c.k7rENE1NlzE0:14055:0:99999:7:::
Note the encrypted password begins with $2a$... in OpenSUSE while in CentOS it starts with $1$... CentOS passwords (MD5?) are understood by OpenSUSE but OpenSUSE passwords (SHA1?) are not understood by CentOS.
First: '$2a' is not SHA1 its Blowfish.
I belive you need libxcrypt support, I'm not sure just google fast I hope this will help you.
# OpenSUSE 10.2 box $ ldd /lib/security/pam_unix2.so
I can't find pam_unix2 for CentOS. It's doesn't seem to be in any of the repos I know of. Any hint as where to get hold of it?
show all pam packages $ rpm -qa *pam* list files for pam $ rpm -ql pam
I believe you need to rebuild pam modules (pam_unix2), see arch wiki.
