I am not able to login to SSH shell as default admin (another users and admins are disabled by default, of course). SCP and SFTP connections work well. In sshd.log file is written this:

20 Jun - 11:56:35[0000052906] (9887e580)SSHD Session <3> : Failed password for admin from (ip adress censored) port 13775 ssh2

... but I used correct password, I am sure.
I think, possible reasons of this error are:
1) admin is located in different context, than all users and servers are
2) our Netware server 6.5 SP7 have been installed into tree which are managed by old servers - nw6 and nw5 - edirectory versions was upgraded before.

Any ideas?
