Had an odd one yesterday that I'd like to share and see if anyone else has come across anything similar.
We have Co:Z SFTP (5.6.0) on z/OS (2.3) with a number of 6 and 8 character users regularly sending files into us. They all have OMVS segments defined in RACF with home directories pointing to USS and all works lovely.
Yesterday a 7 character user id was created with an OMVS home directory pointing to a valid USS directory of which it had all the right access.
Odd thing is it doesn't go into the home directory at logon. A debug shows:
debug3: SSH_FXP_REALPATH . -> //FTPVALU size 0
If I copy that user id to 8 characters with the same OMVS segment it works fine
debug3: SSH_FXP_REALPATH . -> /u/SFTP/VALU size 0
Logging onto SSH both userids present in the correct home directory so it does look to be Co:Z
In /etc/ssh/sftp-server.rc we have "export SFTP_ZOS_INITIAL_DIR=// " coded. The removal of this fixes the issue for the 7 character userid.
We can also code a specific entry for the user in /u/SFTP/VALU/.ssh/sftp-server.rc - "export SFTP_ZOS_INITIAL_DIR=/u/SFTP/VALU" and this also resolves our issue.
Any help/ observations appreciated.
