InvalidGuestLogin on rhel 7 with the good ldap account

Hi,
When it uses pyvmomi for execute a command on a vm rhel 7.8 with ldap account and pam sssd module, the pyvmomi module return vim.fault.InvalidGuestLogin
Whereas it can to connect on the vm console with the same account.
For information, this performs with a sles 12 sp5 vm and with the system configuration.

./VirtualMachine.py --hostname rappdepotrh07lab1
Traceback (most recent call last):

Start with VirtualMachine.py lines 274 and 425, where executeCommand calls StartProgramInGuest, then compare the RHEL 7.8 LDAP/PAM SSSD setup with the working SLES 12 setup. Reproduce the InvalidGuestLogin path and determine the configuration or code change needed for the supplied account to authenticate successfully.
