Please provide the package NVR for which the bug is seen:
krb5-libs-1.21.1-8.el9_6.x86_64
How reproducible is this bug?:
Always
Steps to reproduce
- On a fresh IPA instance move /etc/dirsrv/ds.keytab to /etc/dirsrv/ds.keytab.bak
- ldapsearch -Y GSS-SPNEGO -b "" -s base "(objectClass=*)"
- Under AddressSanitizer there will be leaks in /var/run/dirsrv/
Expected results
No leak
Actual results
Memory leak reported by AddressSanitizer
