Description:

Hi Team,

We are  trying to integrate PostgreSQL (9.6.6) with AD (Active directory)
using LDAP and  facing issues with integration and it seems that issue is
because of the special characters that has been used in the password. 
 
Is it a know issue in PostgreSQL? Do we have any fix for this issue? 

Thanks,
Ashish Puneet
