I'm using a custom perl script, using perl-ldap (Net::LDAP).

I'm trying to connect to my server via ldaps://. On RHEL4 (and CentOS4) this works without problem. On RHEL5, I keep getting "stronger confidentiality required" error messages.

Connecting from an RHEL4 client gives me:

Aug 15 16:51:52 csenet slapd2.3[4105]: conn=1318 fd=15 TLS established tls_ssf=256 ssf=256 Aug 15 16:51:54 csenet slapd2.3[4105]: conn=1318 op=0 BIND dn="<binddn>" method=128 Aug 15 16:51:54 csenet slapd2.3[4105]: conn=1318 op=0 BIND dn="<binddn>" mech=SIMPLE ssf=0 Aug 15 16:51:54 csenet slapd2.3[4105]: conn=1318 op=0 RESULT tag=97 err=0 text=

Connecting from an RHEL5 client gives me:

Aug 15 16:57:14 csenet slapd2.3[4105]: conn=1326 fd=15 TLS established tls_ssf=56 ssf=56 Aug 15 16:57:14 csenet slapd2.3[4105]: conn=1326 op=0 BIND dn="<binddn>" method=128 Aug 15 16:57:14 csenet slapd2.3[4105]: conn=1326 op=0 RESULT tag=97 err=13 text=stronger confidentiality required

I've got the same client configs on both systems, and TLS_REQCERT = allow.

The truly confusing part is when I do an ldapsearch (instead of trying the perl script) it works correctly:

Aug 15 17:00:08 csenet slapd2.3[4105]: conn=1331 fd=15 TLS established tls_ssf=256 ssf=256 Aug 15 17:00:08 csenet slapd2.3[4105]: conn=1331 op=0 BIND dn="<binddn>" method=128 Aug 15 17:00:08 csenet slapd2.3[4105]: conn=1331 op=0 BIND dn="<binddn>" mech=SIMPLE ssf=0 Aug 15 17:00:08 csenet slapd2.3[4105]: conn=1331 op=0 RESULT tag=97 err=0 text=

Anyone have any ideas why perl-ldap/Net::LDAP would be using such weaker encryption?

Thanks,
