[pgpool-general: 5409] Re: pam ldap failure

[Muhammad Usama]

Hi

It was an issue in the Pgpool-II code that was causing this problem. I have
pushed the fix for that.

https://git.postgresql.org/gitweb/?p=pgpool2.git;a=commitdiff;h=c4f816b53b22956c60cf1a78f87d266675c15d43


Thanks
Best Regards
Muhammad Usama
