For the z/OS® LDAP server, use the job name associated with the LDAP server's started procedure as the name of your PTKTDATA profile.

For other UNIX-based applications, such as the z/OS HTTP Server and the FTP server, that authenticate using the z/OS UNIX __passwd() service, the default application name is OMVSAPPL. Therefore, in most cases, use OMVSAPPL as the name of your PTKTDATA profile. However, because an application might change the default value or use the __passwd_applid() service to specify an explicit value, see your programmer for the correct application name to specify as the name of your PTKTDATA profile.
