Sybase ASE connetionString is not working without userName/Password

Question

I am using ASE client 15.0.3 version with dot.net version 4.6.2 and able to connect Sybase ASE DB through connectionString=“Data Source=mango; Port=5000; UID=sa;PWD='abc'; Database='pubs2';”

Is there any way to connect Sybase ASE DB through windows authentication without uid and pwd in connectionString ? ,the below connectionString is not working getting error “Ase Error: invalid authorization specification”

“Data Source=mango; Port=5000; Database='pubs2';IntegratedSecurity = SSPI”

or

“Data Source=mango; Port=5000; Database='pubs2';IntegratedSecurity = true”

Can anyone please suggest?
