Full_Name: Allan E. Johannesen Version: 2.1.15 OS: Red Hat Linux E5 URL: Submission from: (NULL) (130.215.36.68) I somehow missed installing 2.1.14, and was still running 2.1.13. I found that 2.1.15 did not run on one of my servers (but worked on the other 2). Looking back, 2.1.14 had the same problem. 2.1.13, compiled and linked again on that same client still worked ok, so it doesn't appear that libraries went sour. The failure is on a gssapi syncrepl client on an opteron. The gssapi syncrepl client on Intel works ok. The master appears to work ok, too. The ldap server was running on appliance4 and was accessing the master on appliance1. When starting it under debugging -d-1, I got to this: ldap_sasl_interactive_bind_s: user selected: gssapi ldap_int_sasl_bind: gssapi ldap_int_sasl_open: host=appliance1.wpi.edu Program received signal SIGSEGV, Segmentation fault.
