Public key permission while submiting an job using interative desktop app

Hello,

I am experiencing a new problem now after pasisng through many issues. I am using ldap user credentials to access the slurm login node and slurm compute node from OOD server (OOD server also accessed through ldap users with ldap credentials). When I submit a from using interactive desktop app I am experiencing a following error;

Warning: Permanently added 'slurmctl.csc.uni-frankfurt.de' (ED25519) to the list of known hosts.
jsethuraman@slurmctl.csc.uni-frankfurt.de: Permission denied (publickey,password).

I don’t use ssh keys only using ldap user credentials (where we do have list of users in ldap server) but I don’t know why this pops up with this error. Could anyone help me with this?

Thanks in advance!

Best Regards,
Hariharan
