Hi, can i use AD credentials for log into vcops? i am using vAPP.
Yes you can.
It works through vCenter for the standard and advanced versions.
For the Enterprise license, you can use AD users and roles with the vcops-custom interface.
Which version are you running? As Mike mentioned if you are running Enterprise you use the vcops-custom UI to perform a LDAP import under Admin - Security. You can add users to 3 different default roles administrators, users, operators or create custom roles and privileges.
