Description (partial)

Symptom:
LDAP bind request contains extra backslash characters. Example:
2019 Dec  3 15:31:09.327801 ldap: ldap_escape_special_characters Before escaping : uid=Administrator,CN=Users,DC=lab,DC=local 
2019 Dec  3 15:31:09.327808 ldap:  ldap_escape_special_characters: After escaping : uid\=Administrator,CN=Users,DC=lab,DC=local

The bind will later fail with:

2019 Dec  3 15:31:09.342327 ldap: ldap_handle_bind_rsp: (user bzick) - bind for root failed - error Invalid credentials

OR

2019 Dec  3 15:31:09.342327 ldap: ldap_handle_bind_rsp: (user bzick) - bind for root failed - error No such object

depending on LDAP sever usage (AD vs OpenLDAP respectively).

Conditions:

ldap-server host 192.168.1.4 rootDN "uid=Administrator,CN=Users,DC=lab,DC=local"  password cisco timeout 60
