LTM error message / Exchange 2013 iapp

Hi everybody,

we have the same log in our LTM 11.6.0 hf1.

the log written by our LTM is:

TCL error: _plugin_rule_/Common/ntlm - attempt to use empty persistence key (line 1) invoked from within "persist uie "$tmm_ntlm_p""

can you provide the steps followed to address this problem?

thanks,
